I didn't see a response mentioning expat, James Clark's free xml parser.
It's the xml parser which will be used in the next release of Netscape,
and which will form the basis for Perl's upcoming xml support. See
<url: <A HREF="http://www.jclark.com">http://www.jclark.com</A>>. God bless James Clark. I use expat at work
and man it's fast. It's in ansi c so shouldn't be a problem to integrate into
whatever architecture you've got.

it seems like what XML would buy you is a standard, extensible way of doing
this encoding which is not you-specific. I've found sgml/xml to be quite
useful for encoding information in a _reusable_ way; using it here means it
would be easier for someone else to look at your communications protocols
and write a new client or server that works with it.
