Zooko and I hammered out a versioning scheme on the mailing list: http://allmydata.org/pipermail/tahoe-dev/2008-November/000879.html has the discussion.

The action items are:

add remote_get_version methods to our four main Referenceable objects:
storage server
introducer server
helper
chk-upload-helper
add web pages for the URLs referenced therein
add code to call storage.get_version and stash it somewhere
add code to upload to respect max-immutable-share-size
add code to introducer client to get_version and require v1
add code to helper client to get_version and require v1

Mostly done, in changeset:0eb6b324a4fcda2f, changeset:bf06492a90a3cc49, changeset:0fab511be531c6f3, and changeset:3e25efc010876b42. The URLs used as protocol
identifiers are:

The version information is attached to the RemoteReference, in the form of a
VersionedRemoteReference wrapper with a .version attribute.

The upload code has been modified to look for maximum-immutable-share-size
and skip any servers which can't handle the share we want to give them. This
still needs tests, though.

Oh, it according to the most recent comment, this might not be thoroughly tested. What shall we do with this ticket?

changeset:89683a39062edc6e adds the test (confirm that the upload code honors maximum-immutable-share-size), so I think we can close this one completely now.
