A tight coupling is exactly what we need, we have several servers running
different models (and one still running ice 3.3) so a strong check is the
only thing that we can use to prevent unexpected runtime errors. I already
added this new check in OMERO.biobank (develop branch on Github) and I
created a tool that automatically updates the server configuration in order
to add the biobank TAG (I also updated the server installation guide on
Github's WIKI).

Cheers
