When you say "line lump" does that mean "wall wart"

Even with a wall wart I think the first solution is probably the way 
to go. I say this because I think the 500 series are going to appeal 
to a lot of people who may just want them on their own. So an 
individual low cost-ish solution seems a good idea.

Any more news or details on the 500,s - I'll take one of each now :)
