It is a very nice idea: when thinking about it spam filtering is quite similar. Unfortunately my experience shows me that when you get to the small details there is a lot of work (usually too much) when changing the monitored protocol. We have though about applying our technology to non-http environments, and while the underlying technology would probably fit, the implementation itself requires way too much work. Some of the work needed is in the infrastructure elements (parsing for example), but it also seems that when translated to a product the technology gathered a lot of "know-how" of the specific environment it work on.

If you think of it, it's just like UCE/UBE filtering. Maybe it's possible to use software like SpamAssassin and/or BogoFilter to determine if a file is "definitely insecure", "definitely secure" or "not sure". Of course, they would require a whole different ruleset and perhaps some extra training depending on the site, but I do think this may have some perspective. Also, performance wise this may be a good idea: SA and BF are designed for realtime email processing, so I don't see why they shouldn't be able to process a sufficient number of files, even on modest hardware.
