It sounds like a simplistic approach to a trimmed down webservice. Now your approach may be just fine for your current (and future) needs but the devils in the details and if you ever need to expand, you will end up re-implementing apache.

The route I take for trimmed down webservice is to run two different apache instances. One on the normal port 80 and another on a different port (or different machine). That way I can use the power of apache to scale that back-end server with well known and documented techniques.
