My mate was recently in Las Vegas, and had a 4 hour delay.
Sat there with his lappy, and free wifi in the airport watching my xvid share.
If you have the right TV card (it doesn't support many yet) you can also watch TV!
3 mobile have orb as part of their x-series gold package (£10 for 80 hours of orb streaming, slingbox viewing, and 'unlimited' internet'). I am stil arguing with them about the upgrade, as they were giving away free slingboxes last year if you signed up for 12 months.
In summary, ORB is the shit.
Reencodes all your vids on the fly, and streams them (quality dependent on the upload speed) to any PC/ compat PDA/ and compat Mobile phone.
Don't think anyone found a working dreambox remote code though
You could set port forward web-x, and browse that on your phone etc to change channels. SO I am still looking into it. Want three to give me a free one.
Although, the slingbox pro looks ace. HD inputs are a bit of a waste of time as far as uploading is concerend because of bandwith issues, but 4 multiple inputs. I could have my DVD\CCTV\Dreambox\ all hooked up and view it anywhere.
