Hello Peter "plugwash" Green.

I understand who you are.

well, okay, on my XP ( Professional Japanese edition),
it has RRAS on [Service] section.
and I pushed "start", it said it started successfully.
so I think my XP must have the RRAS function, even I dont know how to use it ;-).
you dont have this?
check your control panel again, please.

but I had noticed one issue -
   when I googled with Engilish mode, most site says about Windows server.
   but I googled with Japanese, they say about just Windows, not focused on server.
so I suppose that there is possiblity that only Japanese edition has RRAS.

Anyway, your invention is good.
Lets keep considering BOTH possiblities.
I think it is not time to fix to one plan.

and probably some guy on the earth has same plan.
so what we have to do now is, googling, googling, googling,,,,.
