İlim Uğur is adding metalink support (a way for programs to get mirrors & hashes about downloads) to wget as part of gsoc. we're about halfway through the summer so I thought I'd mention it. it's still a work in progress but İlim's met his midterm goals. Micah is mentoring and says that Makefile.am and configure.ac will be the next step to a wider audience. you need libmetalink: https://launchpad.net/libmetalink and you can try it out from here: https://github.com/ilimugur/GSoC-Project -- (( Anthony Bryan ... Metalink [ http://www.metalinker.org ] )) Easier, More Reliable, Self Healing Downloads
