I have purchased a powered USB hub so when it arrives I will try that out..
What bluetooth keyboard/mouse do you use ?? I have a mini dinovo but that is for my loung room htpc so for the PI I need to buy another one that has the same functionality.. i like the fact of an all in one device ( keyboard and mouse together )
With xbian installed do you then install XBMC on top of that ?? I like that as gives you flexibility to switch between OS and XBMC. Is that what you do ??
I might just buy a pre-ordered case for the PI not sure yet... something neat and tidy and looks good.. the ideas is I want to hang up a LCD TV in my other room and have the PI with velcro so that it can be stuck to the back of the TV or the side... and then play my movies/recorded tv etc... or watch live tv using tvheadend and plex media server of another media server.. do you think i am trying to get too much out of the PI ??
My other HTPC is based on the Asus F1A75 Deluxe motherboard which shipped with a Bluetooth KB/Remote Control.
It was too small for everyday use so I bought a DiNovo Edge and put the stock Asus unit on a shelf until I got the Pi. I tried the Asus it and it worked fine so I continue using it.
The backside of this remote is a full keyboard
The Xbian i installed is setup by default to run XBMC. Since I have another computer right next to my Pi, I downloaded a program called "PuTTY" and I connect and login manually to run console commands on my Pi from the other computer.
It sounds like your plans are do-able. I think you will be able to accomplish what you want, but it may take a little work configuring files and the like.\
Here are a few pics of my latest iteration
