Are the dates for pacsec this year finalized? "November 2005" is a bit 
vague for the airplane tickets. :>

What are you trying to DO with MOSDEF? Some things are quite easy: 
polymorphic decoders and whatnot, and some things are quite hard (but 
quite fun): polymorphic decoders that automatically avoid arbitrary bad 
characters.

Building a MOSDEF for a new arch can take between a week and a month, 
depending on whether you have to build a new assembler and intermediate 
language translator for a new chip, or just a quick mini-libc.

If you have the Canvas Reference Implementation, doing shellcode 
development itself is quite easy. Is there some question in particular I 
can answer?
