Will the user who lease the forging power also earn ARDR in the distribution phase? Does ARDR is paid to all new coins from forging?
There are no new coins in Nxt. Nxt has a fixed supply of coins (NXT). The coins gained by forging are the fees people pay to send transactions.
The forging pools accumulate the NXT fees in their forging account, and that account will be accumulating ARDOR like all other accounts. Are the pools going to distribute the ARDOR? afaik the pools don't distribute NXT until users request payment of their share, so the pools hold some nxt on behalf of pool members. There is uncertainty here ...
Yes, there is uncertainty, will the major pools be distributing the ARDOR to members, or will they keep it?
It might be a difficult task to calculate with so many variables, but it should be possible to calculate with some scripting and the blockchain record. The large pool has already accumulated nearly 21K ARDR so far, so it's not going to be a trivial amount by October 12.

Did the poo operator of NXT-K5KL-23DJ-3XLK-22222 ever respond to this, is he passing on ARDR?
