Freicoin takes the inflationary cryptocurrency idea:

PPcoin is also slightly inflationary, although it offers you an interest rate higher than the inflation rate if you participate in the validation process (basically like mining except you "mine" with your ppcoins rather than with your cpu cycles):

Personally, I don't mind the inflation/deflation argument too much; one thing I would like to see, however, is a coin with a semi-centralized distribution model - an organization bound by contract to give X units to every person in the world. Ripple could have been it, but they went with keeping the coins to themselves instead.

an organization bound by contract

Bound by contract to whom? Who would enforce that contract, and in what jurisdiction?
