Creating a node with parameters passed in.

Hey everybody,
Let's say I wanted to create an article (one of the default content types that comes rolled with D7) with a title of "Testing". How could i pass in parameters to the url that would "prefill" the node add form?

I'm imagining something along the lines of:
/node/add/article?title="Testing"

Unfortunately, this does not work. Does anybody do something similar to this or know an equitable solution? Thanks for any help guys.
