Where can I get my hands on this preprocessor?

Wow - freaky!

Have you got any stats on how such a preprocessor affects Snort?

e.g. how much more CPU/memory load, FP rates, etc.

As far as FP rates go, I mean as it's "just" an AV preprocessor (now
there's an understatement!), I assume it isn't also a SMB
preprocessor - so it isn't translating raw network data back into
files before letting ClamAV loose on it - so the chances for FP must
be higher due to that.
