This would be great, especially if the capped amounts were less than bitcoin's inflation over time.
This could be achieved by having the max block reward for a paid delegate decrease over time, from 50 this year, to less in the future, similar to how bitcoin's block reward halves each 4 years. (Ours doesnt have to have exactly the same schedule of decline).
I think this would help to calm down the investors who have been dumping because they dont like dilution, mostly because they dont understand how large it will be, and it seems to them that it could be any amount.
