Do you really mean round-robin to a bunch of argi, or just
monintoring multiple, balanced links along a single path?
Do any of the balancing methods split a single flow across
multiple paths?  I suppose it can be done, but from what I've
seen of OSPF and cisco etherchannel, specific flows generally
follow the same path, so the retransmit foo will work (as long
as you don't have links flapping).
