It's still a point for me to see where other similiar projects are

And i still think snort is no next-gen firewall either :p
As we saw it's just another way to write rules and use them. Nothing
special on the technical side.

Are you certain? I thought it was mighty enough to handle also streams.
And it might need good hardware but i guess that's an issue that could
be solved. Especially if you want to have more "security" then
performance which might be relevant in some use cases.

I second that. And i would prefer that this perspective is considered
more often.

Well that sounds nice :)
