Satoshi's aren't sendable yet.  Better check facts before making any promises.

Additionally on low volume transactions you will be charged a transaction fee, which I believe is something like 0.0005 in latest client. This is done to eliminate spammish transactions which otherwise would flood the network with people sending nonstop these small amounts.

my older client probably can sent 0.01 at lowest, i'm not sure, the new clients - 0.0001 ?
I haven't tried sending minimums and didn't have interest researching this Q so I may be off on this.
