The Bleeding Snort list is usually the list that gets the new rules quickest recently. They aren't as "polished" as the official Snort.org rules but they work as long as they don't cause too many FP's.

I don't see this licensing thing as an issue really. It won't detrimentally affect the Bleeding Snort list to any great extent and if it were to then that functionaility would probably shift to the snort-sigs anyway.

If it does all go to heel in a handbag it's a great excuse to polish up that rule writing skill and pcre that gets so forgotten because the other resources are usually right up to speed...
