If you consider the possibility that a package may not belong to the owner of R
then you rule out a lot of ways for doing this. One possibility might be a set
of links in /tmp (e.g  R.packages and R.package.xxx ). I don't think you could
write these with HTML, you would need to do that with the R startup script, but
an HTML browser can certainly follow them. There is, however, the problem you
alluded to: one user might clobber another one. As far as I know the only
"official HTML" way around this is with cookies, which I don't know much about
and I'm not sure how you would do it.
