[Zope] ZODB limits

[WebMaster at solari.it]

I'm developing an intranet document management system with Zope/Plone 
and I'm concerned about the capabilities of ZODB. The system is going to 
store many thousands of large files, so the Data.fs is very likely to 
grow up to tens of GB. I'm wondering if ZODB can handle such amount of 
data in its standard implementation (using Data.fs). I investigated 
several alternatives, including ApeLib/Dbtab, but they don't seem to 
work out of the box with Plone (while thay do in ZMI).

Is somebody aware of **fully-tested, real-world** applications with 
multi-GB storage or, in other words, should I stay with ZODB or search 
for alternatives?

Thanks
