That will certainly work for me.

A seperate catalog is probably a good idea however the nice thing is I can
still hook the master search engine to it easily.

I think this should work fairly well.

Adding another zodb should not be a problem. The 2gb limit should not
exist if the box was set up correctly. It certainly doesn't on any of my
boxes. Well we will certainly find out if that is a problem. ;) The nice
thing is that the zodb will just stop growing and will give errors and
which point we mount another one and move some stuff over. Backups should
not be too hard will have to find someone we can do backups with. Would
really help if zsyncer progressed more.

For zsyncer I am not sure. I have found it to be fairly flakey.
