Not long ago I created a wrapper around File objects which automatically
splits the file before it reached a predefined limit.  It could handle
any number of partitioned file segements.  I tried it with FileStorage
and even integrated it in.  That's how we were able to find and fix some
arithmetic errors that occurred in FileStorage when reaching the 2GB
barrier.  If there's interest in the community I can release the code
(in fact, there is no dependency on Zope and it's pretty fast.)

OTOH, I can verify there are production sites that have succesfully
reached around 10 GB in Data.fs size.
