There are already several examples of these out there: problems that require the Sage cell server, or problems using the Rserv integration developed at UBC, for example.
Should we be looking at including metadata in the problems to indicate that they won't run in an out-of-the-box WeBWorK installation? If so, should the Library Browser(s) be filtering these problems from the search by default? What about some internal link to documentation about how to implement these problems?
Any thoughts?
