[R] SAS vs. R in web application

[Gabor Grothendieck]

You would normally have R or SAS run on the server, not on the client machine so
whether it opens a window or not makes no difference.  The window is not on the
client's machine anyways.  The client only has a browser.

Would this option require a multi-user SAS license? (I know, I should check with SAS Institute, but I thought I'd ask anyway. Someone in the list may have done something similar).
