Interesting discussion.  The spot-on "cargo cult coin" critique is devastating to the dev-update-hype driven coins like CLOAK/DARK/XC/BLACK/BTCD/etc.

About Frozencoins, can the same technique be applied incrementally/partially to provide for per-address withdrawal limits?

Withdrawal limits, as implemented by XCN, allow for the 'Holy Grail' functionality of trustless and secure zero-confirmation transactions.

It would be great for VIA to copy that killer application, to the extent possible without an account tree and unmalleable tx.
