Hi Don, thanks very much for your response!
Regarding e00 files, alas I only have .arc files. Though I am guessing
that (and searching for) an existing converter class that should be able
to transform from .arc -> .e00. These both look like simple(ish) ascii
formats to munge between.

Ok, thanks Don. I will see if I can work out the details of the existing
layers (props browser should help) and include one "as is" (if licensing
does not raise its head).
My first efforts and investigations make it seem that this route has
some dependency hell (or some internal opaqueness since the HPAC client
architecture uses OpenMap as just one possible mapping tool set via an
abstraction layer). I will keep poking wires into the problem until the
lightbulb goes on or there is a flash and loads of smoke. ;-)
Cheers,
