in fact it would be really neat to have a webring of such servers in the
each of them could then be running a number of apps, the relevant portion of
the docs,
and refer to each other...
all of them could have same skinning, ...

I would go for starting the ring, and gradually find out how we can automate
and streamline the different servers in there.

The newly cvs repository should be driving everything (also the ring-file)
So maybe it makes sense now, when thinking about the organization of the
various apps in there, to reserve space for the mother-of-all-apps-process
(as vagely described) that can be used to easily publish a number of them on
a server.

I know my thoughts are still a bit weary on this, but my work on the
forrestbot made me think about generalizing the applied pattern to this kind
of stuff... I'll be glad to contribute/co-work on something that could do
