I think the biggest use-case is high bandwidth, high latency links. eg
you have a 50Mbs WAN link to a site in another country, and can never
get more than (say) 5Mbs. Parallelizing the data transfer could easily
push that up to 20-30Mbs

...and there is a "competitor" to rsync that does this - bbcp. Mirror a
directory from hostA to hostB using 'N' tcp streams. Runs like the
clappers :-)
