I met a group from Washington University that was doing this exact thing last year. Check their paper out:

I liked their approach, seemed pretty cool (and they used Snort as their test bed).

Hi,

I would like to know if any of the commercial IDS/IPS vendors are
using hash based techniques such as bloom filters/rabin finger prints
for  fast path filtering.

If so, i would appreciate if links to white papers or any other online
information can be shared with me.

thanks
