I haven't looked at Ice much, and I've certainly never used it for a
real project. For C++, Ice definitely has a much nicer language mapping
since it uses standard C++. I don't think it makes a huge amount of
difference for Python, since the CORBA Python mapping is pretty simple.

For some of the things I use Python and CORBA with, the lack of
something like the Any type would be a real problem with ICE. Anys fit
really well with Python's dynamic typing.

Despite ZeroC's claims about performance, the last time I did any
performance measurements, omniORB was significantly faster than Ice for
most operations:

  http://groups.google.com/group/comp.object.corba/browse_thread/thread/1106eb2c0ae4bc41/cc3468b0c5e1ef8e

Since that post, omniORB has gained some more intelligent string
marshalling code, so in plenty of cases the string performance should
beat Ice now. Of course, Ice may have got faster since then too.

And Ice isn't a standard, of course, which may or may not matter to you.

Cheers,

Duncan.
