You seem to suggest that you can copy the code and put another license on
it. In general you can not: doing so is likely to violate the license.

There are several packages on CRAN that use the 'Additional_repositories'
field in DESCRIPTION (see the "Writing R Extensions" manual for details) and
two of these use a drat repo (disclaimer: I wrote drat, and find it useful;
see http://dirk.eddelbuettel.com/code/drat.html for more on drat):
- lawn
- wikipediatrend
You could follow their lead and just have the code which CRAN cannot use on
an additional repository. Which drat makes super-easy --- and then it is just
an install.packages() call away.
Note, however, that Additional_repositories works only for Suggests: but not
Depends: This has implications for how you lay out code in your package.
