Hey,
I left this community some time ago, because I had to sell my N900. Currently I don't own any suitable devices. What I did though, is that I wrote a remote for the vlc which is currently published in the Windows-Phone-Store. It is build (almost exclusivly) in HTML/CSS/JS. I use Phonegap aka (yeah I know) Cordova to be able to port it to some other OSs in the feautre. However right now, there is no Sailfish OS support for Phonegap, just Tizen.

Anyway, you'll find the sourcecode here.

Feel free to use it as a starting point. Also let me know, if you need any help.

So long,
blck
