[arin-ppml] V6 address allocation policy

OS/2 isn't really a good example; I supported some of that for years.  IBM tried to make "windows" for the enterprise with enterprise bells and whistles; it was to expensive for the masses and you had to be a pretty darn good sys-adim to set it up.  Or maybe it is a good example of what we did with v6?

As to HDTV, the USG provided a cheap shim to let folks decide on their own when to buy an HDTV.  In the case of v6, we forgot the shim entirely; and $40 per app would be really good cheap shim even though we have two or more orders of magnitude of v4 apps to convert now than legacy TV's.

I agree we can probably extend the runout some few number of years; my concern remains that all the new apps are still being written mostly without any v6 built in support for future conversion.

Take care
