Thanks for all the responses, Bernhard, they will certainly
make my work easier!

Okay, well, I will.  I've had the chance since I posted to try some
experiments with generating images using Skencil.  The Skencil part
worked, but the Zope part needs some more coaxing (having trouble with
handling mime types and stuff). ;-)

There is one other Skencil problem, which is that an original drawing
may not all be contained in the .sk file (not all embedded).  This
creates a serious complication.  I'll probably need to find a way to
either embed all content during the upload, or at least generate an
error indicating that the drawing is incomplete. Still working on a
lot of details, but I'm pretty sure VarImage 2.5 will support this
feature, at least "experimentally".

My email access is very unreliable at the moment, but I'll post again
when I have something to show.
