After quick look on this, I think, that probably the most open approach
would be to discuss extracting the physical I/O part from Firebird (the
part that writes pages on the disk, reads them, handles temp sort files,
etc.), create a clean interface for it and let people develop the
encrypted storage, for example.

Comments on the approach?
