This partly relies on all distros actually wanting to use the same
codebase ;-P, I don't take that as a given. Has some potential for NIH
syndrome.

I take it that you mean 100-200 lines of glue code in addition to the
(not yet) separate frontend and backend that communicate via dbus?
Because frankly I'd be seriously amazed if the functionality in s-c-date
could be replicated with so few code.

Having UI and logic better separated would actually make it easier to
bring back meaningful text/command line apps which is a good thing.
