To add to this comment, many pieces of consumer electronics equipment today use surge protected outlets. From my own experience, the PLC bandwidth drops to virtually unusable levels. eg: theoretical 200Mbps bandwidth goes to about 1.6Mbps. I do not think it wise to remove the powerline filtering protection on my expensive electronics gear so that i can achieve higher bandwidth via PLC. It should not be a mutually exclusive choice. One day PLC might actually be useful if the phase branching and line filtering problems are dealt with.

In the US, residential electrical service is via a 240v single phase connection (+/- 120VAC). Inside your circuit breaker panel you'll find one or two columns of breakers. The odd numbered rows are connected to the +120VAC side of the service and the even rows are connected to the -120VAC side of the service. Therein lies the problem for PLC within the home. I found that my home office (which hosts my router) was connected to the +120VAC side of the panel and only a few of the rooms where I wanted to send the data were connected to the same +120VAC side. So what I had to do (you may want to hire an electrician for this part) is to rearrange all of the circuits feeding the rooms I wanted to reach to be on the same side of the 240VAC service. WiFi is much easier to set up in my view.

The proposal of bluetooth and PLC is a promising concept espcially most hand-held devices nowadays are equipped with bluetooth technology. I believe more bridging to other technology as well, such as wifi or zigbee. For example, my LCD TV is already connected to home network via ethernet and it would be convenient to control it via wifi phone.
