pf with any l7 patches or ability?

[Nick Buraglio]

I'm looking for anyone that knows of a bsd project that does something 
similar to to the Linux Layer 7 filter project.  Details found here: 
http://l7-filter.sourceforge.net/  I'm more or less hoping that someone 
has a *BSD project that can classify packets based on application data 
in the connections they belong to or that there is a patch for pf to do 
this.  Is there anything in the works that anyone knows of?
