Synchronizing: gvSIG Mobile & Open Mobile IS

I have created my own blog about the Tellus project (created by Manuel Gomez from Ubikis, Lyon, France). He and Philippe Delrieu have kindly added me as a developer to the project and I plan to add a new way to integrate Open Mobile IS and gvSIG Mobile, and also I'd like to improve the way Tellus deals with geographic data. The database on the server side will be a PostGIS database in my tests. The client side will run on a Linux PDA, like the Freerunner (Openmoko) or the Nokia N810 (Maemo).
