Has Linux anywhere got a tool that will take as input an url point at a file name and return the md5sum of that remote file?
Via HTTP and providing a URL, not short of downloading the file and running the checksum over the file locally, and then downloading the file again and making sure the checksum matches.
Your options for remote checksumming are (1) to have the checksum on the server as is often the case when you go to download an ISO and the checksum is an arbitrary link adjacent to the download link; or (2) have remote-shell access to the machine in question to run the checksum there instead of locally.
In theory, one *might* be able to use the E-tag mechanism of HTTP, but there's no guarantee that it's the md5 checksum, an sha1 checksum, or just some arbitrary identifier. So it would completely depend on the site from which you were downloading.
