Cool, sounds interesting maybe... But what's the rest of the system
like? Is it supported already in the kernel, etc.? We really want to
get standard machines where possible.

That's interesting, but we don't want to be doing non-standard builds
for one architecture. That's not the way we do things in Debian...

As Adam pointed out, it's far from experimental at this point. In
terms of popularity, I'm expecting armhf to overtake most of the other
ports once it's been released as stable with Wheezy.
