As far as I know there is no source download at the moment. The license is: http://www.distributedfolding.org/license.htmlThe software is binary-only ? In that case, it can never become a Debian package itself, at most an installer.
Redistribution is explicitely authorized if not-for-profit in the license, which makes it not free. Couldn't it be a non-free package?
I think it would not change much the structure of the package to make it an installer. Is it necessary per Debian policy? Could it be in main then?
