For example, Ubuntu Mobile is going to be a distro for the MID and I think that it will use hildon as its option. You can follow its mail-list: http://lists.ubuntu.com/mailman/listinfo/ubuntu-mobile
You will see that the majority of mails are about hildon

Besides Maemo developers are making possible that hildon runs on other architectures (x86): http://maemo.org/maemowiki/HildonDesktopPortability

And soon we will see hildon in Ubuntu's repositories: http://packages.ubuntu.com/cgi-bin/s...ll&release=all

Cheers,
