Well I had posted earlier a success story regarding the X10 Lola remote (aka a rebadged ATI Remote Wonder). That's now only partially true. While buttons respond thanks to Bill's atixlobby plugin, there are indeed different buttons on the Lola.
Turns out that many of the buttons are common. For example, the programmable A-F buttons on the ATI are actually buttons like "Artist" and "Genre" on the Lola. And a few aren't equivalent at all.
I've decided that it will be worth the initial effort to program Girder for every button. That will also let me use the volume buttons (which look like left-right arrows, perfect for Music page navigation) and others for what I want.
I'll try and post a .GML once I get it done. Of course folks will have to map the equivalent codes in Xlobby..
