Comment:

 Implemented in Linux by the recv_image and serve_image tools in
 git://git.infradead.org/mtd-utils.git

 Works nicely on 802.11 at up to about 100KiB/s.... the trick to making it
 go faster than that is to persuade your sender to multicast at more than
 the lowest rate available (which it does to improve the changes of
 everyone seeing it). By using hostap on my PowerBook to create a network
 allowing _only_ 11MB/s data traffic, I have achieved reasonable results.
