Hmm... definitely no Windows developer on this end,  but still:

I've recently advertized to a close family member who works in a
regulated environment, Windows only +
Big brother is installing also software company wide,
that you can easily install R and use it without admin priviledges...
and received a very grateful response.
Now Ross makes use exactly of this situation.
I think it would be very nice if ESS on Windows searched the user home
directory as well.
A propos registry; I think we still do not use it even though we had a
(patch ?) proposal a couple of months ago to do it?
