It would also be a nice feature to be able to restrict access to a set of
originating IP adresses or address ranges (as a basic security mechanism).
I've no idea if or how this is supported by the underlying OS.

Some nice option like {accept_from, [{10,1,2,3}, {10,2,0,0}]} would do it :)

In my application at the moment I accept the connection and if it is not
from an allowed address disconnect it immediately. I have seen an unfriendly
client doing retries as fast as it can running on a very fast machine knock
a node over.

Views? Feasibility?
