Hi everybody! I've played around some nights with php and dbus-connection and made a small web frontend to control gmusicbrowser through dbus. It looks something like this:

Quite verbose README for requirements and installation can be found at: https://github.com/laite/gmusicbrowser-plugins/tree/master/web_frontend. If you're interested, I think the easiest way to get this is to clone my gmusicbrowser-plugins repository (or download it as zip) and find folder called web_frontend.

For cloning, run (in console):
git clone https://github.com/laite/gmusicbrowser-plugins.git

Or click "download zip" from https://github.com/laite/gmusicbrowser-plugins

Installing this frontend is probably not trivial for linux-beginners, but I try to follow this thread at least for a while. And please, read the README  :)
