I have just found a tested solution using a new (Apr 2010?) plug-in called STL4SU. I started a new thread HERE so that it didn't get lost in the shuffle.
Just a note on the last bit...I have been using Cadspan for the last 5 years, and to my understanding it has been out there for the last 10 (they are a local company) so I am fairly certain they don't intend to stop service any time soon. Very nice guys BTW.
