Very true, the encryption is based on random probability. so a 1mh/s miner could do it, but I feel I need to test this, I"m going to activate my cpu and begin testing this, I'll run it for 1 week 24/7 and come back with the results, I'll make sure to optimise my server for maximum efficiency... though hopefully no one starts downloading massive files while i'm doing this.
Er....
The phrase "within reason" may apply here. A 1MH/s client? Seriously? Let me know what that settles down to on the "Expected time to share" statistics. I've got a feeling you might get something like 50 days? Bear in mind that means you could easily see a gap between shares of 100 days if you had a bad luck run... Say 6 or 7 shares per year? Over a year I guess you might actually get something back. Not much. But slightly more than zero. You'd be gutted if you hit an orphan block though
