These are some ideas that might be implemented in the future

.oc file suffix#

It might make sense to have a file ending for OpenCoin messages, especially for CoinStacks. This would allow mime-handlers to pickup the file and treat them in a special way.

oc over html#

In theory a CoinStack could come as a standalone mini-wallet that would display the contents of the embedded CoinStack in a readable way, along with ways to renew the coins etc.

The problem is that this would make users open up and trust arbitrary html files. web wallet#

We could implement a web based wallet (using javascript or python in the browser (pyscript/transcrypt). This wallet could be either a single html file, containing all css and js, or we use subresource integrity for this.

This web interface could even be the hander for .oc files.
