Well, almost wireless.  Regardless, there is a radio involved.  Skimming 
through that page and this one:
http://en.wikipedia.org/wiki/Power_line_communication
...makes me think that many more factors are involved then the usual for 
802.11g or n.  For instance, how noisy are your power lines?  Do you use 
dimmer switches in your house?  And, because you are in Europe, how many 
houses are connected to the same power transformer as you are - 10? 100? 
  Do they use similar powerline modules?  How does that effect your 
though put?  Is European power distributed in two phases like in North 
America?  Is your transmitter on the same phase as your receiver?

In data communication there are usually two ways to look at a 
connection.  There are those connections where every thing has to make 
it regardless how long it takes.  Like when you are downloading an 
application.  And there are those connections where missing data will 
can be tolerated, bit late data is very annoying.  Like when you are 
streaming video.  I would suggest you take a look and see if these 
powerline boxes are smart enough to know the difference.  My guess is 
that they have to be smart enough to adjust for different noisy 
environments. And may have a few user adjustable parameters to 
accommodate streaming media.

I don't know if that's a good way to look at it.  Doesn't a ripped PAL 
DVD take more space (i.e. need more BW when playing back) then, say, a 
recorded over the air PAL transmission?

Know the feeling...  thinking I'm going to switch to duel core boards 
before long...
