With the use of Shimano style splined cogs they are obviously not going to unscrew so the reverse lock nut is unnecessary and a standard hub thread can be used for the locknut, this was the route taken by Shimano with the original non-Dura-Ace Uniglide hubs locking sprocket, which used the same set-up although the thread was not extended beyond the first sprocket. By threading the whole driver it allows for juggling of chain line with spacers. As a bonus besides the ability to spin on a freewheel one could use a BSC Bottom Bracket lock-ring instead of the one supplied.

I can't wait to get my grubby little hands on one of these.

For more classic mix and match action I suppose one could install a multi-speed free wheel and a derailleur, after all the axle looks fairly long, just don't forget to buff off those logos and add an oil filler cap. ;-)
