Thanks for your explanation, Satya!

...and the 3 biggies aren't that big, really.  We could have them
fixed quite fast.  RPC2 needs a negotiation mechanism for selecting
the best level of security available at both ends, subject to
configurable minimum and maximum levels specified by the application.
(I assume it doesn't have this, since you say a wire protocol upgrade
is involved.)

Kerberos integration (instead of, or in addition to, auth2), would be
a great such improvement.  This has become especially relevant now
that Windows uses Kerberos -- a venus for Windows that authenticates
automatically, using Windows credentials, would be a cool feature.

I'll certainly want to contribute something -- but I'll first take a
look at things, and decide where I can realistically be of most help.
The documentation is sorely in need of cleaning up and updating...
