Using webservices to upload leads and contacts in to MOD

Hi, We currently use CRMOD and we upload leads and contacts directly in to the CRMOD system using web services, we have recently purchased the Marketing On demand module, and wanted to make sure all contacts that are created from webservices are created in MOD rather than CRMOD, mainly so we can take advantage of the built in dedup functionality within MOD.

 does any one know if we can use web services, to create contacts/leads in MOD directly rather than CRMOD ?

thanks
