No worries, things can't keep cluttered in just one thread.
So what I am thinking is that you can keep mini-blockchains through a redemption of your address balance through your private keys. I had talked to some other developers about how it can be done, the mechanics of it and it would be good to test out and try (whether on PayCon or another Blockchain) so there is the option of doing it.
I hope I'm not stepping on toes by posting this but it's useful information
I also have a couple interesting links to check out.

The method I'd want to shoot for would be something like a redemption script in which you can load your old wallet or convert your keys automatically into the fresh Blockchain. This would be useful incase anything catastrophic happened and you wanted to load the balances onto a new Blockchain, if you wanted to upgrade to another Blockchain and/or cut off all the old data and save valuable disk space.
