How do you mean "embed"? Sorry for naivity on this, but I've only
done that within Gnome so far. Just a link would be fine.

As kmself pointed out, the sensible way to do this is by giving each
client their own R. This makes sense from two performance ways: the
same client is likely to send multiple requests in succession; if they
break their session by doing something "silly", it's their own fault
and affects only them.

I'm confused. Although the front page says you can call Perl from R
_and vice-versa_, only calling Perl from R seems to be documented at
first glance. The python one looks more useful in that way.
