It is outside the scope of the jboss project, we are pure java.
We could provide something using iiop or soap but it is probably not
the best solution.
Somebody was working on an xml binding for .net
I finished a prototype xml binding for .Net this past summer (XIL). It is not yet in the jboss cvs tree because Scott Stark requested I modify it to derive from UIL2 instead of UIL, and I haven't yet made that improvement. The original implementation is at sourceforge under the csil project.
I am hopeful that I can port XIL to the UIL2 form by the end of this year.
