[Thanks very much John, excellent.]

Re: CAT6

I have always assumed there is no significant (home) benefit to CAT6 
over CAT5e, particularly given the additional handling 'difficulties' / 
cost, especially as I never expect to have any home equipment better 
than 1 gigabit, full duplex even, to connect it to.

Have I assumed incorrectly in terms of benefits?
