Why not additionally mimic the OAI interface on the SOAP/WSDL level for 
harvesting purposes? I.e. the SOAP object could provide methods for RPC like 
getRecord(), getIdentifiers() with the respective arguments (identifier, 
until, ...) passed to them. Calling the remote procedures would return the 
respective OAI result.

Has a kind of SOAP-OAI already been implemented somewhere or discussed on this 
list? In fact, the OAI header corresponds to the SOAP envelope paradigm, both 
use XML for data transport. SOAP does not only rely on HTTP, but would also 
allow for asynchronous harvesting via SMTP.
