Cool!

One reason we tried to avoid the direct RPC route was to establish a
strong decoupling between frontends and implementation.  Our messaging
spec is 100% of the api between clients and kernels.  There's a direct
way to get raw kernel attributes for special cases, but by not making
it the  top-level mechanism, we enforce a fairly strong separation
between the two.  We think in the long run that's a good thing.

But there are certainly advantages to the direct rpc approach when
doing rapid development, that's for sure.

Cheers,
