Hooo boy, this concept has been worked over twice in the last year 
and a half, with no real progress or consensus.

There is at least one company that can do this from a hardware 
perspective (http://www.sbei.net), but my take on things is that any 
person/company willing to fund the integration into Asterisk is not 
interested in making such code available back to the community.  In 
any case, there are few people who need a DS3's worth of TDM, so it's 
a very narrow niche.
