In general, the tactics I discuss aren't specific to REST or to Rails. Scaling a Rails application - RESTful or otherwise - is much like scaling any other application: minimize the cost of each request, etc.
A truly RESTful system would make this a bit easier, but it wouldn't eliminate the problem entirely - statelessness, for example, wouldn't help much if your application churns away for five seconds on every request.
