We are extremely interested in these kind of systems.
We, that are the CouchDB developers, sort of tackle
the same problem space, only from the other direction.

Where Kai and Alexander Reinefeld (& co)'s work focus
on the distribution & fault tolerance, CouchDB aims to be
an attractive data store first. It is meant as an alternative
to the often wrongly (as in wrong tool for the job) used
RDBMSes. So CouchDB can be used standalone but
we are planning to have a fault tolerance layer on top
of CouchDB that deals with disappearing nodes and
all that. It would be really really cool if we could
collaborate on this.

CouchDB comes with an HTTP interface, so is
accessible equally easy from all languages,
including Erlang, but it is not tied to Erlang. Since
such high availability systems are attractive for
homogenous environments, a well-known API
is a good idea and you certainly made a good
choice with the memcache API.

Is the interest in merging our systems mutual?

If  there anything is you would like to know, do
not hesitate to contact me (here or in private if
preferred).

Keep up the good work!

Cheers
Jan
