Hmmm, if we need an overall checksum...

 - The server cannot stream data to the client because it has to wait
until it has all of it. Even if our current implementation doesn't
have this, having a protocol that allows streaming is high in my list.

 - Aren't we back to the 2-hashes-will-get-us-sued square?

frankly, a hash collision that has the same content length and over
the same syntax format (html/xml) is so rare as to be... well, not
really something I would expect :-)
