No, I don't think this functionality belongs in DCOP itself. You can do what 
you want by creating a proxy like kxmlrpc. E.g register a client as 
"remote-proxy". Applications can then ask "remote-proxy" for a DCOPRef to 
"remote-object at remote-client at remote-host" which will give you something 
like DCOPRef(remote-proxy,obj#1)and then remote-proxy can relay all calls 
made to obj#1to "remote-object at remote-client at remote-host".

asyncCall might be usefull, don't know how hard it would be to implement it, 
it might require some extra bookkeeping in the DCOPClient to keep track of 
requests.
