It turns out the transition to fractional amounts, which is required for reducing the minimum fee, will not be that simple. It would require adding a new transaction type, because the current ordinary payment transaction stores amounts and fees with 1 NXT precision, not multiplied by 100 as in the account balance. So it will take longer to implement and test. The positive side is that while doing that we can make the fractional part allow amounts much lower than 0.01, so we will achieve much higher divisibility.
This is very good news actually. The reason is 1 NXT is clearly way too big for tipbot, but .1 or .01 is fine, so if it was easy it would have meant a long delay to get the added precision beyond the .01
My latest projections are showing that 1000TPS is most definitely a real possibility to happen, this year. Imagine if the entire economy of a country was run on top of NXT. Even a .0001 fee would generate 6 NXT for every block, which is a lot more than it is now. Those 6 NXT would also be worth a lot more at that stage.
Not sure where it is on the priority list of things, but I would rank it very high to get more precision to NXT.
