As stated in the task, we're very happy to count on your experience in
HL7 v2 and the related python libs to integrate it in the GNU Health module.

We are now working on the migration of current functionality to Tryton
3.0. After we're done with this (within this week), we start working on
the new functionality, including HL7.

Drop by the IRC channel (#gnu-health at FreeNode) one of this days and
we can talk about it. We are talking with Cedric about the best way to
approach messaging engines.

Best,
