Well - here we go...

Attached you will find two files:

rtpmidi.zip -> the source of the rtp-midi plugin
capture.zip -> an archive which contains two captures of rtp-midi-data

The specification that is the basis for this dissector is:
http://www.cs.berkeley.edu/~lazzaro/sa/pubs/txt/current-rtp-midi.txt

The code compiles under Windows (cygwin & vs 6), I have not tried compiling
it with linux, so anyone who wants to give it a try, please do so.

Additionally, I guess that the things I have done in the dissector
could probably optimized. I have just used calls that I got a glimpse
of within some of the other dissectors (rtp & rtp-events, rudp).
So comments on how to improve the code are highly welcome ;-)

Best regards,
Tobias
