[Snort-devel] Is there a snort/libnids alternative

I'm looking for exactly the same thing as libnids.

The main thing missing in libnids is continued reassembly of tcp-flows 
even though there are SPAN packet drops.

A TCP stream flows between client and server just fine (e.g. a 
long http/1.1 keep-alive session).
Some random packets are dropped in the mirrored copies.
When libnids sniff this and reassemble the stream, I want it to leave a 
gap in the buffer where there are missing packets, and continue processing 
the flow. Currently it stops processing the flow.

So I'm looking for an alternative to libnids that hopefully works better 
(and that might have bells and whistles like drop detection, vlan-tag 
purging, ipv6 support, etc)
