Sorry, we keep context-switching faster than I can catch on. I meant to
say that D-Bus is the mechanism that we'll use for the local
applications to talk to the identity service and other similar services
on the machine.

These I haven't thought about yet, and probably won't be the person
doing so. Not yet sure who will.

There will probably be a mechanism to do this, for some value of
'transparent'. There are strong privacy concerns, but for some whitelist
(e.g. the school server), authentication with transparency is a
reasonable goal, and one I intend to support.

-ENOTMYDOMAIN. Also, we're still not devoting any thought past the bare
minimum to the details of server applications, so I think you'll have to
wait a bit to get many of these answers.

I'm still not entirely convinced that's the case, but Chris is a better
person to speak to this. I'm pretty sure we'll provide some form of
package management on the school servers.

This would be very useful work, particularly if you were willing to
document it as it was happening, so it can serve as a manual for other
application developers wishing to do the same to their own applications.
