Can we have a flat file or in-mem storage backend?

I want to use Tracer to demo some Go kit stuff, where setting up a DB is rather too onerous. A simple flat-file or in-memory storage backend would be more than sufficient.

If you'd like to contribute an in-memory storage, I would merge it. You can copy the Null storage and fill in the blanks. An implementation of server.Storage automatically implements tracer.Storer, so you won't need to write a transport and can run the server and the instrumented code in the same process, if you wish to.

I, too, am interested in an in-memory storage, but if I have to write it myself it might take a couple days.
