In order to store favorite stations you need a user-ID to identify you. Because it's a PIA to login from a NMT using the remote every time you visit this website I came up with another way of identifing users; a simple user-ID which you need to setup once in the URL on your NMT.
The downside of this method is that anyone can view your favorites if they know your user-id or randomly use the user-id of other people.

In order to use favorites create a new Webservice on your NMT with the following URL: http://hdx.i-v-o.nl/6791, and you're done!
