Yep.

Nope. Javascript can't manipulate images in any fashion other than a
linear stretch -- and linearly stretching images is functionality we're
moving *away* from in OpenLayers because it had too much behavior that
users couldn't accept.

If you want that, you want to set up your own tiles -- or use another
service on the web which provides up to date, unprojected tiles.
OSGeo used to host one of these, but I let it lapse after recent
planet.osm troubles. I can take the time to set it up again -- then
you'd just point to http://t1.hypercube.telascience.org/tiles? , with a
layer of osm-4326, which would allow you to use tiles that are
compatible with all the 'unprojected' services out there.

If I set it up again, would you use it? If so, I can set it up again.
