I've actually been playing with Maeda's KML with the idea of eventually 
trying it with snort. It's unclear to me if there will actually be a 
performance enhancement by running snort in kernel mode.

I've started to write a stub library that I can use to link with snort 
so that I can take advantage of KML and directly call kernel system 
functions instead of using the Linux/i386 interrupt 0x80 calls. While it 
appears that there can be a savings of several hundred cycles per system 
call, in the grand scheme of snort, it may still be negligible.
