Why? Have you tried it? This is one of the core features of MapProxy: answer requests in a different projection that the cached data.

I have tested it with you example, and it worked.

Again, I succeeded with your example. It loaded a lot of tiles caused by the meta tiling and the difference between EPSG:4326 and EPSG:900913, but it worked.

I don't know why you MapProxy installation hangs. Maybe the Paste HTTP Server doesn't support any concurrency on Windows? Can you request http://localhost:8080/ while you are waiting on the "hanging" response?

PS: Please answer to the list as well.
