It would help a lot of people behind small pipes. I have been encountering problems with git-clone when the link is unstable. After the smallest error, it erases everything and you have to retry from start, which is quite frustrating and expensive. At least, downloading a tar.bz2 with FTP would be easier and a lot more reliable. Also, people could download it from their workplace and bring it home.
