Also, the quoted bandwidth for those devices is a total bandwidth over your power lines, not bandwidth between two devices, so for an 85mbps powerline networking kit that's 85mbps total backbone, regardless of whether you install 2 or 16 of them, each additional device adds to the load on your 85mbps backbone. So you might find that the network load exceeds the capabilities of these devices if they are all used at a similar time, which they inevitably will be...

Just read this thread for the first time, and I have to say that my first thought was HOMPLUG. I use homeplug extensively, and I believe you could comfortably have 6 or 7 people streaming a DVD at the same time without network dropouts. The homeplug devices now go upto 200Mbps, which would obviously improve things further. yopur obviously not intending to stream any hi-def content, so I think the cost of the homeplugs will actually be cheaper than cabling (and less invasive).
