Note: "permalinks" may not be as permanent as we would like,
direct links of old sources may well be a few messages off.

sorry, but that is not possible for DRBD-replication. 802.3ad does just 
improve performance over 1GBit, if you transfer data to multiple 
hosts/mac adresses, because it does balance the streams via modulo 
operations of the mac adresses of both peers. As Ben Timby wrote, the 
one mode that provides multiple link aggregation for a single tcp stream 
is balance-rr.
