This seems a hard argument to make given that popular corba implementations
which support firewalls via tunneling techniques have been around for a
number of years, yet have not had much impact on corba's (lack of)
popularity.  The reason that http & friends have had the impact corba had
hoped for has to do primarily with the fact that they're simple
("web-weasels" don't typically write CORBA servers); other reasons include
ubiquity, performance and tools (emacs, vi, or notepad all work pretty well
along with one of the many free, stable httpds available to anyone).

Certainly this can be done, but one has to wonder why one wants to do it.
I've played extensively with manipulating DOM structures remotely via CORBA
(see http://www.objdev.org/index.html for some details) and the bottom line
is that the granularity of the DOM is inappropriate for significant use in a
distributed system.  You're better off in nearly all cases simply firing a
stream of XML at whoever needs it.  

I think that one could happily integrate all sorts of wonderful XML-derived
benefits into a CORBA environment by having both stream and remote
invocation interfaces (I'm working on such a system now).  However,
"layering" CORBA on top  of XML will prove to yield little of value except a
reminder of how precious performance really is ;->
