As is, Xepdmgr will refresh the whole display. It would happen once in a while (say every second), not streaming as for the current keyboard. I think that Cellwriter may work, but in a less less comfortable way than the current thing.
Xepdmgr mus be configured in such way that it does not cause to many redraws: a high cpu load would disturb the drawing...
EDIT: Nice to see everyone online and typing
