Why not? I'd be more than happy if *all* my servers had this feature.
Allowing no more than 2 login attempts via SSH from each IP address in a
60-second period is not something that would affect or inconvenience
any of my users, but it *is* something that would slow down, annoy, and
otherwise impair the jackasses who keep trying dictionary and scripted
attacks against my servers.

What do you see as the downside to such a feature? Of course one could
adjust the specific settings (say, no more than 5 attempts in a 60-
second interval if you want to be liberal), but I see no harm...

Cheers,
