Hello Question regarding the downloading of the english xml dumps of Wikipedia for archival purposes its 4gigs which is alot to download ever time new dumps are released so any way that diff patches or xdelta patches will ever be released along side the full dumps so I only have to download those patches containing only the changes rather then 4gigs of more data? (Imagine all the bandwidth saved!)?

Link to xdelta here http://xdelta.org/ and diff/patch are located in all modern unix based distros (linux/bsd and such)
