Networking of AC power lines, How well does it work

[adamcanto]

I want to add a gaming pc in a room without cable of phone lines, I was looking at linksys's AC power networking kit, Say it has data tranfer speeds of up to 85mbsp!
Has anyone tried this settup?

I have used this for normal networking and it works fine although I use it only for the internet and the transfer rate is never going to exceed 6mbps here, even with with a following wind!
