That is somewhat of a religious issue. Some really like JSON-RPC, others
enjoy REST backends. You've already received a couple of opinions. I'm
fluent with JSON-RPC but not with REST, but I thought that REST was only GET
requests. If that's the case, it can limit the amount of data you can send
to the server, which may or may not be an issue for you.

If you use a different port number for the backend than where your page
loaded from, your requests to the backend will be considered "cross-domain"
and you will encounter the same-origin policy issues. In particular, you
will not be able to use XmlHTTPRequest, the standard transport for most
background requests. The biggest implication of that is security from your
backend point of view. Does your backend need to know who (what web page) is
making requests of it, or is it basically open to the world? If the former,
that's much more easily done when you have the same origin for the web page
and the backend, so you'll want to somehow arrange for the same port number
to be used for both.
