Good point. The interfaces are different, from what I gather, since that
is working with HL7 v2.x. The patient searching is... meh. I mean,
I just used the search/search_read/etc. methods on the models. I suppose
they could use some of the code that creates complex tryton search
queries from arguments. Although it's rather ugly. Hehe.

Awesome! I'll take a look! HL7 v2 is more widely supported (I think), so
this is good stuff.
