[Bro] Using workers without SSH possible?

[Sven Dreyer]

Dear list,

I'd like to operate 3 workers in different subnets. Unluckily, the 
network connection between manager/proxy and these subnets is really 
slow (around 500 kBit/s) and has frequent outages.

Is there a possibility to synchronize the nodes without the necessity to 
use SSH? Perhaps by a frequent file transfer using rsync?

Thanks and best regards,
Sven
