Try opening a new project on savannah.gnu.orrg or gna.org
Please don't put it in gnumed CVS
(this is not a statement of its usefulness, it sounds like a significant 
achievement)

Why a directory? If both are talking to postgres, Argus could simply
grab/dump HL7 messages from the gnumed schema.

Mind you, this means you x thousand lines of Java to do what 2-3 pages of 
python code could ;-)

If you are using Java just for the IDE, please look at some of the python IDEs 
which
IMHO are just as good.

In terms of hacking Argus, what would be very good is weaning it off the HIC 
PKI into
GnuPG or (preferably both) an open X.509 crypto library.
