as far as i understood it, the max cps value in the dcc options is the overall setting for all dcc sends. if i set it to ~8092 the sends are limited to 8kb/s, but this applies to all sends. if i have 2 sends, they are both at 4kb/s.
but this is not what i want.

The -lN switch limits the transfer rate to N Kb/s, ...

this is what i want to do. and it doesn't work...
