The nasty effects of the 'big' powerline data transmissions, like
internet access are know. Essentially all HF in the area is disturbed.

But what is about the small powerline devices. The small boxes you plug
into your power outlet in you basement an attic to link the two
computers there. Example device: http://www.phonex.com/prd_nw14.htm

Anybody has experience with some of those ?
