As far as I know, you can trigger third-party replication by using
DataGridlets. You can pack files in DataGridlet using
addRequiredFiles() call and the DataGridResource
(SimpleReplicaManager.receiveDataGridlet()) will automatically fetch
them from the RC if those files are not at the resource.

Hope this helps

Cheers

Srikumar.
