ah well - I guess I was talking in the idea future world of EHRs being 
everywhere, not today. In the future of a shared care, community-based 
EHR I would expect both types of carers you mention to be entering the 
data into the EHR, not in some other system... maybe I am wrong here.

Anyway, I accept what you say - let's just say that now and in the 
future, in many instances, the data for the transaction types i mention 
will come from GPs and other carers accessing and modifying the EHR.

yes - whatever application being used.

well I wasn't talking about messages here - I was talking about 
communication through a network-visible API, which is what you get with 
.net, SOAP, Corba etc.
