Quite fairly and accurately stated, Brian. While CORBA is not inherently
slow (one of the top 10 CORBA myths floating around), many newcomers build
slow implementations in their initial efforts. This is a difficulty we want
to relieve in the CORBAmed Quick Start kit under development (as our meager
resources allow) over the course of this year.
There are a couple experts who do CORBA/M bindings for a living. Terry
Weichmann at ESI, [EMAIL PROTECTED] and David Loveluck at
Intersystems, [EMAIL PROTECTED] come to mind. Perhaps they would be
willing to offer some pointers. From a CORBAmed point of view, we would
like to see Intersystems, ESI, and others(?) develop a submission for a
CORBA/M interface standard.
