Brad,

No, I haven't built any lighting instruments.  My circuit is a DMX to
analog voltage converter.  I know that these are available commercially,
but I wanted to gain some experience using PICs and writing DMX decoding
software.

No, I didn't use any public domain software.  In fact, I have been unable
to find ANY public domain software on how to receive/decode DMX512.
Almost like it's top secret information.  Maybe I was looking in the
wrong places. :)  However,  I did receive many tips from various people
on the lighting developers list.  By far the trickiest part was figuring
out when the break signal had been sent.  I ended up using the ninth data
bit as an indicator for the break signal.  If the ninth data bit was
clear, then we have a break.  If it was set, then we have either a start
code or dimmer data.  I have been told that using this method is not very
reliable, however, I have not yet had any problems.  In case you're not
on the lighting developers list, here is the URL for more information:

If I can get my code commented and in a more presentable state, I would
be more than happy to share some code snippets (same goes for you Keith).

If you have any further questions, let me know.
