I would beleive in the future this could very well be an option. The issue has always been being able to find a stable download to try and actually in the past it was extremely hard to get a working server install to be able to write this up. Also in that mix is hardly no servers run the software capable for this technology. Michael has had a few posts over the years on this.
I tried at one time to find a download to try since I have a server totally in my control but was never able to find a valid download. I know Michael I think tried getting it working on his server and had trouble. So I guess if I can find a valid download and able to actually get it installed maybe I can try seeing what can be done.
