I've heard rumors from several sources about a "multi-Gig" network interface model that can push "1Gbps < some-rate < 10Gbps" over Cat5e. It would be a forklift upgrade to take advantage, but it was an interesting compromise that would be appealing for an "older" installed base. And while I'm replying... we are just doing single runs, but we're doing Cat6 in recent projects and no 5e yet. We haven't jumped to Cat6A (yet). We considered double runs with 11ac coming, and we're an Aruba shop (they have two ports on newer APs) but we're rethinking some of that mainly due to density / coverage collapse (if 11ad rolls out, with it's 60Ghz band, coverage area/interference get to be a major pain). We've also ditched 62.5u MM fiber for 50u OM3/OM4 similarly (there was a ton of 62.5 done initially that is absolutely useless beyond 1Gbps).
