DownloadService seems to be missing some functionality, or the spec and
implementations are too vague to follow how to do what I need to do.

While running an app, I want to check to see if part of the app has new updates
to download. I don't care if we have ever downloaded the jar previously and it
is in the cache, I want to check the server to see if my cached file are up-to-
date. Then, when I know the status of my file, I can make a decision as to
whether or not I want to load the new updates. There currently doesn't seem
like a way to do this.

Here's a scenario:
My app is large and has several 'parts' which may or may not be used by the
user. When the user does decide to use a part of the app, I want to do a "just
in time" install of this part of the application. To do this I want to: (1)
Query the server to see if there are updates for a particular "part" based on
version or timestamp (this would be done without downloading anything), (2)
Make a decision based on server feedback, (3) Decide to download the latest and
greatest files.
