1 client, 1 wallet = you will never have your first bitcoin!!
My worries are:
1 client generates so little parts of a bitcoin, that you will never be able to transfer them to a "central" wallet ..
Why can't you merge several clients to cooperate on the "same" wallet so you actually have a chance of getting a transferrable amount (0.01) within a life-time??
It seems to me like you will have to adjust the "minimum send-amount" before any mining will make sense when Bitcoin goes "gold" ..
It doesn't make any sense to run it on several computers if none of them will never generate a bitcoin that can be transferred ..
Your bitcoin balance will always be 0.00000 untill the first 0.1 is generated right? Where can you see the payouts in realtime with "bitcoind.exe" without just waiting patiently for your first bitcoin ??
