have a look at tools like:
netsift www.netsift.net/ -- now a part of cisco, but check out

honeycomb - www.icir.org/christian/honeycomb/index.html
uses suffix trees to evaluate honeypot dat to build signatures.
in short its been done, there's some room for improvement (via hueristics
and better speedups via algorithms), but it's proven to work.
