Be forewarned - Storable does not provide forward/backward compatability. That is, if you upgrade your perl, there is a significant chance that all your stored objects will be unretrievable. If you switch platforms, it's almost guaranteed (use nstore - that may help).

At least, that was my experience with Storable, oh so many years ago. I'd be happy to hear that has changed.

We use storable extensively on many different systems with very little trouble.

Version problems are potentially still there, but only if a newer version stores a data type that an older version cannot handle. (it now will try to handle the data from the newer storable instead of just croaking)

I second your comment about nstore though. I'd highly recommend using nstore by default. Having to convert a couple million stored objects because you add a 64bit machine to your farm of 32bit machines sucks.
