What we really need is a universal bar end/thumb shifter for all
single cable-pull gear hubs, with a removable indexing disc that could

to make this a succesful product, and most of us would be willing to
fork over *a lot* of money for a really nice shifter if we knew we
could keep it on the bike after future hub upgrades.

I hear what you're saying but I hope my hub has a good few years in it
yet! I'm not convinced any shifter would out-last it.
