This is all the work of Pavlin Radoslavov.

AFAIK, it's not on the radar.  If you are interested probably best
talk to Pavlin.

The trade-off for C++ vs C is the same as for any application.  There
are many many of discussions on this in textbooks and the www.  We're
not likely to present anything new here.

This is a concern as far as getting community involvement.  Hopefully
documentation and code examples will help.  We're interested in making
the C++ code available in other languages, perhaps through SWIG, to
make faster prototyping and testing viable and to provide access for
people who don't like C++.

As far as efficiency goes, it obviously depends on what you are
measuring.  We have a largish memory footprint but are aiming to run
on commodity PC hardware and assume that memory is not an issue in the
same way it is if you are running an embedded box or something like a
Cisco.  Likewise, we have plenty of CPU power on the target boxes
(lowest end in our testbed is a 486).  Standard profiling tools for
performance can be applied as and when it becomes necessary.
