We were able to get this working -- sort of.

We got ahold of a X-windows client that does full color and GDDM APA
graphics (which is really nice)... and now, all of a sudden, it works (then
again, this one understands WSF calls).

The Mitek gateway, though, won't do auto-selection of terminal types, so we
still have a problem.  It's not as serious as it was before.  Mitek says
they're going to have a fix for the multidrop problem by Tuesday of next
week.... if they do, and can provide automatic selection of terminal model
(with a default for vt100 terminal clients) then perhaps we can get things
resolved there as well.

Then again, maybe not.  Who really knows at this point.

I've been asked not to release the source of the X-windows client for this
yet, pending cleanup of the code and a real release.  I'm sure we'll see it
on the net eventually.

Btw:  It's is REAL good... I really do like it, even though it is a little
rough around the edges at this point.
