[Zope] Any working experiences in using compression (for storage)?

We are in the need to put more text information into Zope's database without exceeding its file-size. I know there's a product CompressedStorage out there, but it's kind of old. Hence I'd like to know whether there's succesful experiences on using it and/or compressing stuff inside ZODB. Which is the best approach for a task like this? Thanks in advance, Ausum
