Well, clearly we have at least 2 forks, and at least 2 forgers. It is not enough for a healthy coin.
I also think like you, that base code for web wallet is very close to the NXT code, NAS is essentially a NXT clone, as the pretended added features are just in the Windows client, WinNAS: BlockDice, Chatroom, BlockLottery, ...
Some features, like the ports used, can be changed in the 'nas-default.properties' file, and we can also change the name of directories and files to avoid references to NXT and substitute them by NAS. So we can easily do a new package of files, a new minor revision without changing code, just filenames and text content to make a consistent package.
So, if we get enough nodes to run the server, and we agree in one fork, the coin can revive. The fact that development is stopped is an advantage in order to trust the coin. The initial distribution is already done, and the ones who have more stake can donate few of them for bounties or promotion.
It is very interesting for me the idea of a cryptocurrency with frozen development (although, if it is really just a clone of NXT, further independent development could be done).
What do other people think?, are there more supporters for this idea?, contrary opinions?
