This is very interesting, thanks. It really does seem to be as easy 
as I thought!

So the only remaining question is about the power supply itself. 
Obviously I don't really want to have 5 power supplies at node zero 
for the 5 ePODs and anyway I doubt very much that the ones supplied 
with the ePODs would be sufficient over a 50m run. So what I really 
need is a big power supply that can support 5 ePODs concurrently 
(hence bigger current draw) and can supply adequate voltage over 50m 
of cable (hence higher voltage to allow for drop).

Does anyone have an idea where I might get a suitable PSU and also 
could anyone with the elecronics knowledge tell me what spec I should 
be looking for (I assume it all comes down to Ohms Law, but I 
wouldn't trust myself to do the calculations).
