Ich guess that it will not be a big issue to change from a low bandwidth situation
to a high bandwidth. Maybe it will take a while before the information propagates,
but that should be OK. IMHO there would be more problems switiching back to low
bandwidth mode.
Maybe a solution would be to try a slow approach throtteling bandwidth: to stay with
the example of 3000 to 100 kB/s: I'd try to go down one third of the speed every 20min.
(BTW, 3000-100=2900 ;-) ). This way you could likely avoid too much throtteling of
inbound connections, even if the information is only slowly propagating.
