Does it work with other alt coins? Seems like a great idea. Please count me in for a chance at a free one. Thanks.
Yes it does

with coins like NXT, it works a little different as you will get the full wallet UI as if it's running on your own device. For all other coins, we've built a web UI that works with the JSON-RPC API of the daemon.
We also take suggestions on coins to add to our list so please feel free and suggest them.
