Realistically, what are you going to be running at 1.01Gbps inside your 
home at any given point?

Yes, this may or may not be a rhetorical question.

Show me a single production-level 10Gbps port that runs at 10Gbps :-).

Yes, those are just plain old IP routing numbers.

Add IPSec and QoS, the numbers fall to between 20% - 40% of that.

Well, the initial question is what is going to drive that kind of 
capacity in a home setting?

Unless you are providing some kind of service at some kind of scale, I 
just don't see homes blowing through 10Gbps, never mind 1Gbps.

I just bumped my FTTH service up from 100Mbps to 200Mbps, and aside from 
faster Youtube uploads for my DJ sets, I'm struggling to fill it :-).

I have a mate up the road who just paid for a 1Gbps FTTH service because 
it was the same price as a 100Mbps one. He generally lives between 
900Kbps and 20Mbps.

Gigabit-level FTTH services for the home, I feel, have always been about 
marketing ploys from providers, because they know there is no practical 
way users can ever hit those figures from their homes. But because users 
want to "feel good" and "brag" about their Gigabit home connectivity, 
they'll pay for it. Heck, if I were a consumer ISP, I'd do it too :-).
