Is that the upcoming casacore-2.0.0?  Quoting from their homepage:

    "There will be a new major release (2.0.0) soon containing
    significant changes."

I have heard people in debian-astro list talking about casa. I bet there
are interests here.  Besides, we (the airelinux developers in the Cc
list) are eager to get involved.

Please keep us updated on this collaborative effort.  It would be nice
if we could hold a video conference to talk about it.
