Hi Martin,
In addition to what Duncan writes: I think winscp does exactly what you
want. You can copy objects from/to linux, but also edit files from linux on
the winduts machine without explicitly copying (of course you do copy the
file, but is done automatically).

Use save() and load() to create and read binary files containing the objects
you want to exchange.  Use scp to move them between systems. 
(Or sftp, or something else to move files.)

Not that I know of.  You just use the command line utilities via
system() or shell().

Not with base R.  There are some front ends written by others that do this,
e.g. RStudio.
