yes, it works wonderful.

But there is a huge but.

It works wonderful as long as the data volume is low.

The problem is that the powerlines are not shielded. Every bit of data 
going through a powerline transmit a signal in the radio frequency 
range. The frequency depends on many factors.

The main problem is that it will interrupt the usage of those 
frequencies by their legal owners.

The moment you hit the frequencies used by the military they will find 
the source and stop it.

They use this also in many countries to read their own meters. But the 
large scale usage was or is blocked by the owners of the affeced 
frequencies.

You do not need much software to do it as the hardware speaks already 
TCP/IP.
