Title: Allow to add fs in options

Hi,

I had a need to implement my own virtual file system inside Node.JS to serve static file.
I have been able to do so, without being too invasive, by overriding fs.

My use case was to serve files contained inside a zip, but this allow lots of uses cases, such as serving files contained is a database.

Would be great if you also find it usefull.
