Hopefully I'll get to play with this later on in the week..

But here are the things I know I need as part of my business:

-The ability to specify which python to use to build, install and run
zope with. Our production machines have various version 1.5.2, 2.1.X,
2.2.X, etc installed. I must be able to specify the location.

-The ability for each instance to have separate Product directories.
Some users want plone, some don't. Some develop their own software.

-The ability to start/stop zope without access to /proc (or the
equivalent on other unices) on Linux.

I don't know if the changes made affect any of the above ... but it
would suck major #$W%% if it did. Oh, and part of my business if hosting
zope ... if you are wondering where the above (off the top of my head
list) comes from. Other than that it looks like the changes will be good
for me.

Oh and some way to have multiple zope versions installed at the same
time would be great as well. :-)
