Given that the DOM has an IDL mapping, writing distributed implementations
of it should be easy.  Due to some of the choices made in that mapping,
however, it's a little less clean than one might hope.  Specifically, the
IDL and Java mappings are incompatible.  I had brought this up before in
both this and the DOM mailing lists.  Stephen McConnell from the OSM
(http://www.osm.net) was kind enough to explain why this was the case and
what was being done to address it.

In the meanwhile, out of curiosity, I wrote a set of adapters that provide a
"bridge" between these inconsistencies in the Java & IDL mappings.  I've
used these adapters to remotely manipulate DOM objects using the
stripped-down CORBA implementation that comes with JDK1.2.  My experience is
that you're not likely to be too pleased with the performance
characteristics of such an effort, but it's pretty interesting to play with,
and for some uses the performance characteristics may be acceptable.  

If anyone is interested, I'll be happy to send them a copy of these
(extremely rough!) adapters.  Regards,
