Why not do a snapshot of the blockchain and create a new V2 coin containing all the old coin's addresses with balances intact? Clam coin did it by taking snapshots of the bitcoin and doge coin blockchains. All you have to do is import your bitcoin or doge coin addresses to get an amount of clam coins proportional to your original balance.
Do you have a link or example you can provide? I like this idea but it is easier to visualize in practice. I also know the guy that did the ADT swap but he wanted 3k which is what he charged Zack way back in Jan when all the Alts were hitting their peak.
The clam coin source code is available here.
