That'd be great - and something particularly well suited to a group of people 
from a non-english speaking country :-)

Not sure if that's really all that worthwhile. What's the reasoning behind 
this one?

Yes, I suppose this would be good.

Already done. (mostly).

Could be done, but note that if the source gets disconnected (e.g. because of 
network errors), most sources will automatically reconnect on the old 
mountpoint. Whether that _matters_ is another question.

These are quite a lot of work, but it's interesting in many ways, and would be 
a wonderful feature to have. It's also a substantial amount of work that 
wouldn't really touch the rest of the system, so it's particularly well 
suited to being done by an independent group.

This is something I'd like, but my HTML design skills are somewhat lacking (it 
always comes out looking ugly :-)

This is already being done on win32, but RPM and DEB packages for linux 
systems would be good.

My plan doesn't really extend in any concrete way very far - but if we know 
people are working on one feature, then we can stay away from that part of 
the code until your bits are ready. 

I'm happy to answer questions about whether I think particular features are 
useful or appropriate. I don't think merging changes will be a major problem.

We have two mailing lists here (icecast-dev at xiph.org is entirely appropriate 
for this sort of thing).
If you want your own private website/mailing list for your group, then you 
should set that up yourself. However, you're welcome to use our existing 
infrastructure for development discussions.

As for cvs - we're generally happy to give access to people who have shown an 
ongoing interest in developing, and have submitted at least a few 
high-quality patches. Again, however, if you want to have your own private 
server, you'd have to provide it yourself - and we won't give cvs access to 
people who have not proven their ability to contribute sufficiently good

There are already a few commands implemented - they currently use GET. 
However, another useful small project would be to extend the HTTP parsing 
infrastructure to be able to cope with POST requests. The current code has a 
lot of duplication for each individual admin command, extending this to a 
more powerful and generic admin system would be a good project.

I think docbook would probably be the best approach to take with this. 
However, if there's a compelling reason to use something else, that's 
generally fine.
CVS access for documentation works the same as for writing code - if you've 
contributed good stuff, we'll generally give you access. Until then, docs 
should come to the mailing list, where they can be discussed, etc.
