Steven can explain the details. Basically: it works, it is simple to
understand and to work with, and it seems to be flexible enough to support all
current needs and seems to be flexible enough to support future protocols. It is
currently under review based on community feedback.
I didn't have time yet to do carefully inspect the latest version of the
multiproto. I suspect that nobody did it yet, since I didn't see any technical
analysis of the current proposal.
I'll carefully review multiproto proposal during my trip, and compare it
with the Stoth's proposal.

We'll have some sort of panel or speech for the attending audience of the Video input
infrastructure miniconf. The API analysis will happen with the Linuxtv
developers that will be there.

As I've already explained, merging today or after Plumbers won't make any
practical difference. The upstream merge will only happen after 2.6.27 being
released, due to the next kernel window for merging patches. This is a major
change at API and claims for a carefully analysis.
