TMSM should work both with a local store AND radius.  If there are 
problems with either that's what needs to be found.  This thread came up 
because David Nelson wrote:

Kaushik, Keith and I proposed a method last summer that would have 
precisely addressed the 2nd sentence in that paragraph.  I believe this 
leaves David Nelson's question somewhat unanswered.
