You know what: This is the only coin I've seen in a very long time that's almost entirely innovation. Keep on with it, because the number of liteclones and dogeclones out there is getting out of control - finding people with actual brains is not an easy job!
And I like the honesty - "heat death of the universe" :-P I feel like some projects are gonna take that long myself sometimes.
Also I will add my tuppence: Data storage is a REALLY bad idea, unless you have a method of removing it through some kind of voting mechanism, or it's personal and securely encrypted. To allow unencrypted data in the blockchain is incredibly spammy - the BTC blockchain is already 18GB. Imagine that if there'd been data compressed in it. Perhaps if you ran a second distributed data store or something, and THAT was encrypted, with an opt-out on storing it for people with legal concerns... Although that has its own problems.
The legal ramifications if some sicko spams your blockchain with images of child porn could be huge....
tl;dr: I think storing data in the blockchain is a bad idea.
