Hi,
the MNE nightly builds available at the martinos center are now public
and available
on the MNE download page:
http://www.nmr.mgh.harvard.edu/martinos/userInfo/data/MNE_register/index.php
For now, it's only the Linux 32 and 64bits binaries.
It should allow MNE users to have access to the latest features and bug fix.
Best,
Alex
