Is this much different than the current system of life + every changing number when Mickey is going to expire? This small change wouldn't impact the big corporations, but it would start letting smaller things fall into public domain. Then, after a while of acceptance, you do something like limit the number of renewals, make it price prohibitive to renew more than 2-3 times, or limit transferability. Or you could go for a big bang change and hope you have a critical mass of votes.
