As I said....there are too many datfile authors and no real standard for an update url in a datfile header has been done yet. It's not that easy as it may look. We have to care about security and update rules. Which protocols (ftp, http, https, etc..) should be supported, how to be sure that the url (since it's freely editable) isn't modified) etc...etc...Too much things to care about at the moment where nearly anyone got too little spare time.

Though it's been discussed before....it won't be forgotten.
