Ack. It's called beta.
I do need people interested in using it to try it out *seriously*, though.
Chris hit quite a wall even when testing it for a while. I've got some
data from that but the lesson is: don't think it's ready for (your)
production if you haven't run it in (your) production successfully.

And there will likely never will be speed improvements over regular ZEO.
I was a bit shocked when I looked at the actual slowness, but then
again, I didn't think about performance at all.
(In standalone mode there is a slight chance that you can load
read-requests off to multiple backend servers. Haven't tried it, though.
And it won't be available in co-op mode.

Nope. The blob directory (even with regular ZODB) is a managed area like
the data in your Data.fs. (You wouldn't go editing that data with your
editor, would you?)
