For testing, why not doing that on maggie indeed.
But I insist on the fact that maggie should at no cost run real public services.
Apart from that, I read that SVN was frequently broken wherever it is provided.
Installing it is one task, but maintaining is another. It would be nice if
Timothee can devote time to install it but it cannot work if he does not have
time to also maintain it on the long run.

I'd propose to setup a Woody in a chroot'ed environment in our spare machine
(ie. Maggie), and have Timo install a SVN setup and try to write the Savane/SVN
backend (account creation, backup, etc).
If 1) it works, 2) we have a free IP to dedicate to this service (ports:
http{s}, ssh, ?), 3) we can buy a dedicated machine, it could be a new official
Savane service. I'm not firm on #3, we'll see the machine load by then.
BTW, I've known Timo for a long time and trust him. He maintains ID Software's
GPL'ed level editor Gtk-Radiant as well as GNU/Linux ports of their (closed
source, yes:)) games. He's been closely involved with SVN and its community for
more than 2 years.

I have noticed that some other sourceforge forks have started providing SVN
access. I don't know which codebase gna uses exactly.
http://developer.berlios.de/forum/forum.php?forum_id=4718
Anyway, to answer (partly) your questions:
- storage: GtkRadiant repository (https://zerowing.idsoftware.com:666/) has
4320 revisions, and uses 1.1Gb.
It's a fairly large repository, as it was converted from a CVS repository,
after 4 years of active developement, and is used to store binary media as well
as source code. SVN tends to be bigger though. Got an account of 120Mb ->
150Mb. Expect a size increase around 20%.
The storage is berkeley db, so it's a single large random access file.
- backup:
SVN provides a hot-backup.py script which can be used and extended. It does a
hotcopy to duplicate the repository. I run it croned daily. Only doing
hot-backup when the repository changes.
- CPU load. for regular usage, backups, viewsvn .. hard to estimate. The same
box ( P3 600Mhz ) we started GtkRadiant on CVS, we are still using with SVN.
SVN generally performs better for users for your server CPU cycles. Word on the
street is that it's less CPU intensive ( HD bound? ) + 'costs are proportional
to change size, not data size', which is not true for CVS.
- security / permissions etc.
the svnserve protocol doesn't offer much for permissions. It has an anonymous
mode (no write), and otherwise uses the permissions it is executed as. They
plan to improve on that, but the DAV way offers fine grained access already.
I can't say I'm a big fan of ssh for transport. It makes things fairly hard to
setup for windows users, which is my main problem with it. DAV over https, with
client certificates .. makes things about as secure as an ssh access anyway.
- web interfaces to repository:
ViewCVS: Requires the python bindings. I gave up using it on GtkRadiant, as it
locks me up (
http://sourceforge.net/tracker/index.php?func=detail&aid=895294&group_id=18760&atid=118760
)
SVN::Web: uses the python bindings. Is more bare-bones than ViewSVN, but a good
alternative. That's what I'm running now, but it has scalability issues on
repos with a lot of branches.
Chora: requires php, word is Chora as experimental SVN support.
The web interfaces will likely be causing most of the load.
- cvsreport-like:
There are contributed scripts in the SVN repository. I have one with web URLs
which I can contribute. It's much easier to write that stuff with SVN than it
is with CVS.

Let's try to detail a bit, we need :
- storage: what is the disk usage ratio between a CVS and SVN repository for
the same source tree ? What are bandwidth issues (lots of small scattered files
? heavily random access ?)
- backup: svnadmin dump or hotcopy ? Need some insight (time, load,
compression).
- CPU cycles: difficult to estimate. Right now we only have 90 projects and the
CVS server is lightly loaded (0.1 average). What is the load ratio between CVS
and SVN for the same source tree and usage ?
- init: need to hook a 'svnadmin create' in the group creation backend.
- security: preferred transport will be SSH, user & group rights should work as
they are now. Expecting WebDAV when there is a dedicated server for SVN.
- helpers: ViewCVS 1.0-cvs supports SVN. Needs a cvsreport-alike.
Comments/addition welcome.

do you have a roadmap at this point?
