nmdb is a network database (dbm-style) for controlled networks that can use
different protocols to to communicate with its clients. It supports TIPC, TCP,
UDP and SCTP.

It consists of an in-memory cache that saves (key, value) pairs, and a
persistent backend that stores the pairs on disk.

Both work combined, but the use of the backend is optional, so you can use the
server only for cache queries, pretty much like memcached.

A library is provided to interact with the database and the cache in a very
simple way. Python, D, NewLISP, Ruby, Bigloo Scheme, and Haskell bindings are
also available and come with the distribution (although except for the Python
bindings, the rest are not widely tested).
