nice thing,
but if I missed please repeat how do you deal with actual cheaters in those two scenarios:
I.  max pool connections can be filled up with 'empty' miners -> i'm not talking about botnet, just i.e. thousand (or more) miners -m 0 and and just wait for some coins xD,
II. or do it with purpose to fill up pool and eliminate possibility for other miners(people) connecting to pool -> getting sort of solo mining carrier with no or very little concurrents -> which effects many things.
