A completely understandable point of view.  But I don't think this will be
the case (at least, that's what I'm hoping).  I read the Bovine-RC5 FAQ,
and though I can't double check what I read right now (the site hosting it
is apparently being buried by net traffic), I thought I saw something
about limited disclosure.  Or was that wishful thinking...? 

Heck, I'd even consider an NDA, with the stipulation that code not
relating directly to the network communication or transport is publicly
publishable.  That way, the Bovine folks keep their security, and those of
us with more esoteric hardware can still port and participate. 

(I've never been a fan of security through obscurity, but I realize that
the developers are probably too swamped to deal with a public review of
their protocol.  Besides, this is a short term protocol, and it's not like
we'll be relying on it for years to come). 

I first asked about source availability on #rc5 about a week and a half
ago.  Do any of the coordinators or developers have time to comment?
