As an alternative to X, perhaps the use of NeWS
with PostScript imaging might be a fun choice.
Sometime ago I built a foreign interface to NeWS,
including support for Jot, the NeWS Toolkit text
editor.
The following shar file includes the necessary support;
it also includes participant.self and synthetics.self
as possible idioms for building applications. (I should
mention participant.self and synthetics.self are
incomplete; they belong to a project that is still happening.)
I would be interested in any experiences you may have
with this stuff.
