Good idea.  :)

With my vendor hat on (and you know what color that is), I need to be able 
to identify a release of CTDB to ship with products.  I can back-port fixes, 
as needed, but I need a foundation from which to work.

With my developer's hat on, I have been digging into the code to familiarize 
myself with it so that I can contribute more.

I am interested in the libctdb piece, and testing.

Most all all, I want to make sure that CTDB is nicely polished for use in 
Samba cluster products.
