I'm not sure. I think it may have been used for Exchange5/Outlook 
connections, but you are right in that I don't know if this works.

Wines sockets support is good though, far better than its builtin DCOM. 
Based on what I know of the DCOM network protocol, I don't think we'd 
have any problems with it.

Only issue would be if you needed NT only features, as only DCOM for 
Windows 98 works natively on Wine.

Off the top of my head, I can't think of any big issues. Maybe dcomcfg 
doesn't quite work yet etc, but fixing any problems that arise would be 
much easier than migrating to a totally different OS, or bringing our 
own DCOM up to scratch ...
