Heh.

How is the ZEO RAID project going, anyway?  It seems like a good idea 
and I don't think it actually depends on ZEO, does it?  For example, I 
wonder if it's possible to create a RAID storage around a set of 
RelStorage instances.

I got a report from one person who put RelStorage behind a ZEO server. 
Apparently it works fine, though I haven't tried it myself.  Maybe we're 
finally reaching the point where we can choose from several ZODB storage 
components and connect them with ease.
