When getting the EventMove server side event from the month control, it passes back a EventMoveEventArgs object. this has 'OldResource' and 'NewResource'.
When events post back there is no resource value set. It would seem that this can't be possible without setting a DataResourceField property a-la Scheduler control?

You're right. This property is there because EventMoveEventArgs is shared by all controls. This is not the best design decision but the API change would break the existing implementations.
The 7.0 release will introduce a few API changes that were neccessary (e.g. BeforeEventRenderEventArgs classes are now separate for each control) so maybe this change will be done at the same time.
