In the absence of vector data I agree that a controlled way of auto-tracing the building outlines (a JOSM plug-in would be ideal for me) is the way to go.
For my area, unless something like this comes along there will never be building outlines in OSM as the local demographics mean mappers are in short supply and I can't imagine that those that there are would want to manually trace 10s of thousands of buildings anyway. I don't think the "we shouldn't sully OSM with OS data" argument stands up as looking at my area (Devon) most of the coastline + almost all names of natural features and numerous other stuff has come from the NPE and 1st Edition maps. The StreetView coastline and waterways data is way better than what we currently have here and unless there is better data coming in the near future then we should trace this stuff in asap.
