Something we are working on right now is an implementation for subid tracking. This will allow you to track siteid as well as another text field which could be dynamically inserted on your site. So you could track which users on your site / app are making the most JSE for example. This will tie in with the upcoming API release so you can check balances via siteid or subid.
This should allow webmasters to integrate JSEcoin into their sites. One partner has suggested providing JSE stats to his users and then using an API EXPORT call so they can transfer the JSE they have mined on his site to their own JSEcoin account.
It opens up lots of possibilities and if you have any suggestions / queries let us know now as this is in active development at the moment.
