Re: Some testing that I did on the testnetwork, my findings.
Gaming the system by including 1000 or so recently turned over BTC to bump the priority as described in my post above still works of course!
Or managing how much priority you spend on a transaction. The software would have to know your future plans to know whether to spend your priority now or save it for later.Forgive me for suggesting complexity, but the "priority" of input coins could be tracked back more than one block to make some sliding average. This reduces the effect of "temporarily devaluing" money by transferring it.
If you look back ten hops and found no "old" money, then there is frivolous jiggling going on. It also creates a new type of complexity attack.
