 "dchassin":A number of additional improvements should be addressed simultaneously. Specifically:

1) The ability to play and record multiple values concurrently to and from a single table.
2) Support for histograms.
3) Support for triggers.

Please record others here as they identified.,

 "dchassin":Progress has been posted to trunk in anticipation of knothole.  Export seems to work fine, but import has the same initialization problem stream_in and checkpoint load (not really surprising).  Work will resume after knothole.,
