Excellent on all of the above points! The C in /lib/* should be mostly
XP, so you might want to look at just using the whole common lib... but
there might be some excellent reasons not to for win32 stuff.
Realistically, any XML parser should do... just use whatever is most

I should have spoken up earlier on file transfers :)
I'll try to write up something more concrete soon here, but here is where
I've been heading with file transfers:
Yup, that's right... let's use HTTP/1.1! It already has EVERYTHING needed
to handle any type of file transfer, and it's commonplace, and it works.
Here's how, simple version:
user x sending file to user z
x selects file to send
x starts small HTTP/1.1 file on high port for THAT FILE ONLY
x sends z a special message(abbreviated):
z recieves message and uses HTTP/1.1 to GET file
HTTP/1.1 can do resumes if it get's broken.
ICQ/AIM transports could impliment "translator" daemons for it
Recieving client could just spawn browser to fetch file
Happens in background, leaves Jabber connection to work normally
This could be simply a URL message, not specific for files
I could go on and on, but I'm outta time :(
A special module could be written on the Jabber server to use this
functionaliy for a "file archive". The client would send a jabber message
to the module and ask for a repository, this would be configurable
obviously so only special users could use it or have size limits. The
module would reply with an: http://serverIPaddress:port/. The client
would then PUT files up there via HTTP, and authenticate them with the
users username/password. Then it would send out the location to GET them
like any other file message as above. This would allow you to send files
to offline users, as well as send files to groups of users, just upload it
once and they all download it. It is also a solution for transferring
files if you are going through a firewall. Actually, it could end up just
being a normal apache and a special module or similiar... and you'd have
your own personal webspace...
There are some issues here yet, but I think this is the best way to go in
some form. I've really gotta sit down and think this through clearly and
get it written down, but hopefully this will get the discussion started :)

Yup, just didn't get a chance to do that yet...

Ask away, discussion is good!
