Shame... I was thinking yesterday that if the Plex developers would just provide the remote ID's that Logitech has used, we could add these manually into the setup of RB. I then realised you can't manually add new remotes... they have to be paired and that means you have to have the physical remote (or even worse, try to use a single remote and cycle through the codes!)
The only way I can see this working is for the dev's to provide the codes used, then for IOSpirit to add the equivalent into RB.
It would be a nice selling point for RB though as I'm sure a lot of Plex users will ultimately want control of other aspects of their Mini.
