Yikes!  Now I'm feeling a bit daunted, as well. ;-)

Perhaps an asynch solution based on select() would meet those needs as
well?  (Please see related thread.)

Since we can connect to netcat (or other listeners) from GCL, I've been
sporadically trying to figure out how to connect something to the 'other
side' of netcat and thus get netcat to pass through to GCL.  No luck so
far, but personally I'd definitely like to get a somewhat usuable hack
like that going ASAP.

Maybe I'll try using Python for this, though that seems a bit *too*,
well, kludgy. :-/

But hey, if it works and is transparent, i.e, GCL neither knows nor
cares, why not?
