We're working with a very similiar architecture here at Lawrence 
Livermore Labs, building a control system for a new laser project. The 
supervisory GUIs are being written in C++/Motif, while most of the rest 
of the software is Ada95. The connection between the languages will be 
CORBA. The platforms are a mix of Solaris and VxWorks machines.
