haven't tried the package you mentioned. However, i it's very easy to
implement what you want, in about 10 min.

you can call several external programs such as linx, w3, wget, curl,
GET, to fetch the the source of a url, then create a buffer and insert
it there. Just wrap it with shell-command-on-region. I think the
following tutorial covers it exactly:

• Elisp Wrapper For Perl Scripts
  http://xahlee.org/emacs/elisp_perl_wrapper.html

a pure elisp solution is also easy. Just call one of those elisp
packages that fetchs stuff over network. e.g. look at the installation
instruction in ljupdate mode.

Getting the url for the input of fetch is easy, by thing-at-point.
