I'm not sure what you mean by server independent. Do you mean you don't
want a solution that requires you to run a separate server process?

It does work with Python. I've built it for Python 2.3 on Windows NT.
There are instructions in the PCbuild subdirectory of the Python source

Within a single process, any number of threads can access independent,
consistent views of the database. If you run a ZEO server, then clients on
any machine can connect to the server to access the database. It works on
Windows and Linux, and I'm familiar with several installations that have
databases with > 10GB of data.
If all you want is a shelve interface, you'd probably do better with
BerkeleyDB. ZODB provides a more natural interface for Python programs --
it just stores objects -- but it does have a different programming model
than shelve. On the other hand, ZODB is faster than BerkeleyDB for many
