I wouldn't want to calculate what it'd cost to replace all my switches with 25G capable ones.. then all the network cards.. You'd have to have a really specific application to justify it.
Just cost me 1K to replace 3 NICs, 1 router, and 2 switches to freaking 2.5Gb.
10Gbps used enterprise equipment is pretty cheap on eBay. Biggest problem I've had is getting compatible SFP+ adapters for the NICs.
Flexoptix reprogrammable tranceivers are a godsend for that. We use them almost exclusively at work and so do quite a few of ours customers (Universities and other places of higher education). But it's probably hard to justify the cost of a reprogrammer box for a household. You can buy their transceivers pre-programmed though.
FScom has something similar, but I can't vouch for those, never tried. Their patch cables are fine though.
