One can definitely view the IDL as a programming language independent
interface description and the IIOP as the somewhat agnostic wire
protocol. In the larger cross-platform picture, however, I'm not sure I
see the ubiquity of CORBA and/or DBUS. One of the reasons web services
are kind of appealing to me is that the infrastructure needed to support
them seem to be built in on many platforms from the small to the large
and from the free to the commercial.

I agree the performance may be something to question, and I'd definitely
be interested in real numbers that apply to typical accessibility
