Hello Eddie Conner,
Currently OpenAccess ORM can be used with Silverlight only through some kind of a service.
Also there are no plans currently to have the OpenAccess runtime run in Silverlight.
You must have in mind that even in OOB mode a Silverlight application still has limited rights. You can however use Isolated Storage to store information while offline. You could use xml to store your information or you could look at this new but promising project:
I hope this helps. Do not hesitate to write again if you have more questions?
All the best,
the Telerik team
