The XEmacs and cygwin netinstaller has three install options: "Use IE5
settings", "Direct connection" (or something like that) and "Install from
local disk". Option #2 never work for me, but #1 does. I suspect the R
installer can do something similar: offer the two options (with and
without), and somehow test if the connection (to CRAN) works. If not,
prompt the user to try the other option. My take is that this option should
be (semi?) permanent: If it's needed, it's needed all the time for that
installation. Wouldn't it make sense to have the setting written to some
file in, say, $R_HOME/etc, that tells R to use that option, instead of using
the command line argument?

Would what I suggested above be easier than this? Not that I have any clue
as to how to do this, unfortunately...
