I have a growing list of changes to libsnert and the other milters. I 
had intended to release those in Auguest, then delayed till November, 
and now December. Every time I think I'm about ready to start the 
release cycle, something new (as in a new bug or change request) comes 
along that makes me hold off. In other words, I held off fixing 
something like the MD5 signatures, because I keep thinking I'll be 
releasing any time now, so why do it twice?

Trying to keep 21 of them up to date, plus test and publish milter-bw, 
plus support issues and questions, plus publish my latest anti-spam 
product (which has been my primary focus these past 4 months) has proven 
to be very time consuming juggling act.

Scalability essentially and ease of configuration. Its also less 
resource intensive and easier to manage than trying to maintain an NxN 
set of connections. So currently, setting up a VPN that proxies 
multicast packets between remote machines/network is the suggested solution.

I might implement an extension that can broadcast UDP packets to 
specific hosts outside the current network segment, which would solve 
the remote/different networks issue.
