My plans for Vegas are settled -- I'll be at BlackHat USA 2007 for the week and then DefCon 15 the weekend following. If you want to meet up for consumption, imbibing or conversing, or all three, drop me a line.
In other news, I've been insanely busy with work but I've got two very cool projects that are well underway. The first is a ruby morph of various projects in other languages -- dpkt (python), NetPacket (perl) and libnet (C). I've taken the functionality of all of these and made some big improvements (IMHO). The second is a project that everyone seems to need but nobody has -- SSL certificate lifecycle management.
More news when I have time.
