Lot of thanks to Ilya SAVERCHENKO for his valuable comments. Service Grids (Federations of managed computing resources) trust Users and push Activities, while Desktop Grids (Loose opportunistic Grids using idle resources) trust Applications and pull Activities. So, there is no interoperability at all. Interoperation can be achieved only by using a Bridge specially designed for this purpose. Detailed description of the Bridge marshaling Activities from Service Grids to Desktop Grids is outside the scope of this Use Case : The User wishing to submit an Activity only needs to know that this Bridge exists, and trust it. Other Actors of this Use Case do not even need to know that this Bridge exists.
