I'm on a 256k DSL. I have HTTP textures enabled. I still see many intermediate texture levels.
Also, for large textures, switching to PNG would likely increase the size of the transfer, which is not good.
On the other hand, since both "old" JPG and PNG support progressive decoding, why not use PNG for lossless textures and JPG for lossy ones? Then you don't lose anything.
