Well, good luck. I don't know a lick of C++ or real crypto coding, so as interesting as I find it all to read and watch and write essays about, don't expect any help from me. I hope you succeed in getting some of the features in more general use.
But this system (or an equivalent or superior one) isn't accepted and likely will not be for at least several years. An alternate currency could do it today.
But also risks there being some minor problem with the unpublished Zerocoin proposal which de-anonymizes everyone who ever uses the functionality. Since laundries/mixes currently seem to be working pretty well, it's better to be conservative and get it right, than push for it to be implemented right now and in 2 years, watch every transaction be de-anonymized.
The bitcoins that I had set aside for a Cryonics contest two years ago (and were unredeemed) are suddenly worth a lot more.
Details: I had added 10 bitcoins to get things started, and there were 4.75 worth of additional donations. These were partially lost when the hosted online wallet that I was using (MyBitcoin) was hacked, but 49% was recovered. As of today, after refunding part of the donated money, it is now worth 5.2675. I will be adding from my personal store to bring it up to an even 5.5. At $140 per coin, the new total is $770.
I've decided to follow the buy-and-hold strategy for at least another year, since it worked so well. I don't have exact details on what I'll do with it, but it will not be converted or spent for at least one year, and will eventually be used for promoting cryonics in some way.
Some things I have in mind if it gets big include:
