what the namdenergy plugin does is simply building custom input,
then run NAMD and grab the output. if you are a little proficient in
VMD scripting, it shouldn't be too difficult to either rip out the guts
of this procedure and make it work for your needs, or - even better -
add the hooks for what you need in addition.

i don't see how this would work in a general NAMD run.
the Tcl scripting support in NAMD has a very different
design and purpose as to what VMD does.
