Though, it is interesting to note that no-ip's Linux/UNIX client is
actually in C:

http://www.no-ip.com/downloads.php?page=linux

The key piece is int dynamic_update() in noip2.c; it does a pretty
simple HTTP request.  Of course, as with all things the devil is in
the details, so I'm not claiming this is any easier because it's C
code.  The binary footprint is only 100K... (and no perl!)
