I know that this is not what the resumption of transfer mods do, but
I think that some people may be overlooking the fact that pkgsrc has
had the FAILOVER_FETCH definition since 1998:

revision 1.154
date: 1998/09/01 13:15:29;  author: agc;  state: Exp;  lines: +63 -69
Amend the fetch:  target, so that the distfile's integrity is checked
with the additional checksum only if FAILOVER_FETCH is set (this does
not affect the checksum:  target at all).

It's used all the time by the bulk build mechanism - it ensures that
the distfile is the correct one, and, if not, will fetch the distfile
from the next site until it gets the right one.
