Are you confusing his frame with the TT version perhaps?
No, there is actually a little more room to move it up or down a couple millimetres due to the fact it's not 100% vertical, working out the magic gearing, plus halflink (if necessary) and a little adjusting is all it take, probably half a day worth of work if you're a little on the slow side.
The amount of room in those dropouts is negligible in my experience. Chain stretching alone will negate it. Plus it wouldn't've made for such an entertaining thread!
