It is far less reliable than a single ftp/http from a good server if the
download method gets chunks from multiple servers of which some are good
and some are bad. The unreliabilities of each chunk(-server) are
multiplied here. A chunked download without chunked checking isn't worth
the bother IMHO.

Especially if the single failure is as bad as it possibly can.

I had wget once wipe a download for me at the 2GB limit (on 128kbit
cable, arrrgh). I didn't use it again for anything serious until that
was fixed.

Of course, rsync always works reliably and as a bonus, fixes things up
too.
