Thanks for the feedback, all. I'll be away for Easter, but I'll be 
reading up and linking things to the web-site after then.

I haven't looked at Magma.. yet.. but if it's an OODB then it's more or 
less just for storage, right? That's an important part of what I want to 
achieve, but the more important part is getting remote messaging and 
object replication working. That's tricky.

Does anybody have a link for this? It's a bit hard to find.

I shall.
