So that prediction turned out a little ambitious, this is the first chance
I've had even just to tar it up and post. There's been absolutely nothing
else done to it since I first played around with it, don't expect too much
to work but with a bit of time it's realistic that it could be made quite
usable. I've tarred up my /usr/share/freevo/htdocs/ folder in it's entirety
for simplicity. It's based on a svn checkout from May (details below) so
beware if you're replacing your install with this. You'll see I've just hard
coded the section for whole house / multi room control as a mock up but I
have an idea on how that could work in practice and again it shouldn't be
too hard. To test it out browse to
http://localhost:8080/iui/samples/freevo.html, substitute in your
ip/hostname to browse from your iphone or ipod touch. I've left the old
library alone from what I remember so that should still work too. I hope
someone finds it useful or at least interesting :)
Hi John,
Looks like you miised web_types_jm. Just got around to looking at
it my self.

Here you go. It's so long now since I looked at it I'm not sure if there
was anything else, hopefully not. I'd love a bit of feedback or even for
someone to do a bit of work to bring it on as I won't be looking at for
a few months.
