So does that mean if the provider no longer supports the PDFs (Amazon after they stopped selling PDFs), I would still be able to access the PDFs. I'm not referring to ones already orphaned by Amazon, that would be too good to be true, but to current and future purchases from various vendors.
Your protection scheme sounds similar to the one from eReader where the DRM info is locked into the document not the device.
