I'm working on a replacement engine as GSOC project, both named captures 
and modern Unicode support are implemented. I plan to wrap up a public 
beta by the next week, to get some early feedback.
In terms of speed in general it seems to be on par with PCRE, but I 
haven't done any pattern-specific tuning (which PCRE surely does).
     I looked over all what .NET supports, and right now new engine has 
support for the most of it's syntactic riches (including character set 
operations) albeit with slightly different syntax.
Exceptions: (?(expression)yes| no)  which looks like a hack, (?# 
comment) and setting flags in midair (?im).
I'll definitely add free spacing syntax mode (see perl) and setting 
flags though.
Anyway, if you are wondering if I missed any other cool regex feature, 
just ask :)
