I guess it ultimately depends on how the DB will handle the blobs. For
example, hSQL has a problem with large files (I tried with something a bit
over 3M), and a OutOfMemoryError (with an empty stack trace ...) was thrown
(and was not caught, so I made the exception handling in AbstractStore a lot
more robust).

With some DBs, storing the content is the database will never be an option
(that's why it's important to transactionalize the filesystem store).

I volunteer for doing some work on the stores, including :
- Developing a new JDBC store which would extend the current store and
handle J2EE connection pools (XA or standard). The standard JDBC stores will
remain as the defaults.
- Improving the filesystem content store to support transactions.
- Study the feasability of developing a filesystem descriptors with support
for transactions and versioning.

I plan to have the first two ready for Slide 1.0.15.
