Well not yet :-(. I had to leave the EMF-Live thingy for now because of
time constraints but providing an EMF-Only implementation (by replacing
my UBean-stuff) is still possible.

The current EMF-Model is a read only one (though one can easily connect
UBean-Notifications and EMF-notifications) so one would double the
memory when having a live model.

The current EMF-Model and the UFaceKit-API also don't match 100%
currently because I had to stop development a bit lately because of time
contraints. I'm currently restructuring the the UFaceKit-API a bit to
use Interfaces everywhere (this helps us later to write an EMF-Live-Only
port).

I'll keep you up-to-date when the EMF-thing is back on track (my test
case is the AddressBook-Demo) but this has to wait until ~ Mid of February.
