Gee, you left out HP: HP has bindings to Xlib, Xt and Motif. These are
bindings to the C implementations (no need to reinvent the wheel eh!).
Also, I don't believe that EVB has bingings to MOTIF. I've heard they are
only Xlib bindings and are for the Mac.

Tried email, it didn't work.
Interfacewise, we tried to keep the interface as close to the C interface
as possible, changing things only when they made sense Ada-wise, such as
the use of enumeration types and the like. It's not that we wouldn't want
a clean implementation of these products written exclusively in Ada, but
the real question that comes up is who is going to constantly roll the Ada
implementation each time X changes and how long will it take them to get
newer versions to markets. Our approach and processes helps us keep pace
with the changing X versions.
If you want more information about our products I suggest that you contact
