So, just as a quick reminder. The pre-BSDCan developer summit, in =
Ottawa, is in=20
May and I wonder what it take to persuade either someone from Tilera or =
the=20
CMU effort to turn up for a day and brief the FreeBSD developer base. =
You can
use devsummit@freebsd.org to get more specific details of the devsummit.

I think this would be an important first step in finding someone from =
the=20
developer base to drive the FreeBSD porting effort and BSDCan is =
probably
quite interesting on it's own.

Cheers,
Mark=
