It's always seemed to me that the difficulty with hypermedia controls is not how to have your server expose them, which is straightforward enough, but how to have your client do something useful with them. It basically means writing your client as a state-graph navigating agent, which makes it closer to AI-ish programming (not surprising, since the argument for REST has been that web services should be structured more like the human-browsable web) than the input -> output or interactive event-driven paradigms that most programmers are more conversant with. Yet the books and online evangelism etc. for REST that I've seen don't really address this issue.
