The Department of Energy is funding the implementation of Rx/TCP and
IPv6 along with many other long sought after additions to the OpenAFS.
Descriptions of the projects and the estimated delivery dates based upon
the grant funding are listed on the OpenAFS roadmap.

Discussions of protocol design issues will take place on the
afs3-standardization mailing list.
