There might be, as soon as we get it into the main line of ZODB. Chris 
and I are working on this every now and then. Due to some feedback we 
got recently, we'll integrate the blob branch into main ZODB in 
approximately Mid-August.

Humm. That's either a bug or a problem in the pattern of how to use 
blobs. I'll try to look into it. Do you think you can check your changes 
on Zope 3 into a branch so I can have a look at it? Alternatively I can 
use a patch.
