What about incorporating LaBrea? http://www.hackbusters.net/LaBrea/
LaBrea is a program that creates a tarpit or, as some have called it, a
"sticky honeypot". LaBrea takes over unused IP addresses on a network and
creates "virtual machines" that answer to connection attempts. LaBrea
answers those connection attempts in a way that causes the machine at the
other end to get "stuck", sometimes for a very long time.
It currently creates a "tarpit" to trap scans to IP's that aren't currently
being used. Maybe someone could come up with it a way make Snort and LaBrea
work together. Snort could handle all packet captures while LaBrea provides
IP's for the attacker to get tangled.
