Your table broke up in transit so it is not clear to me what you were saying

I think the most interesting thing might be a binding to the VA Fileman DBMS
(a MUMPS application) and to existing open source healthcare applications in
the VA VistA. For this, Greg Kreis or Gregory Woodhouse might be of help.

Actually, there are a couple of free (although not open source)
implementations of MUMPS and a project to develop an open source MUMPS.
