Have you already seen these documents?

https://tahoe-lafs.org/~zooko/lafs.pdf

http://code.google.com/p/nilestore/wiki/TahoeLAFSBasics

https://tahoe-lafs.org/trac/tahoe-lafs/browser/trunk/docs/specifications/mutable.rst

https://tahoe-lafs.org/trac/tahoe-lafs/wiki/Capabilities

If you did not previously see those documents, please let us know
which ones you did not already see. We are trying to learn how to
organize the documentation so that people can find the information
that they seek.

It is a lot like the Tahoe2ServerSelector described on
`wiki:ServerSelection`_ and `wiki:TahoeTwo`_, but it has been extended
by the notion of "servers of happiness", which are documented in
`docs/specifications/servers-of-happiness.rst`_.

The source code is in `allmydata/immutable/upload.py`_ (for immutables
only, by the way).
