Take a look at Advantage databaseServer. Andy Kramek wrote some articles about it.
Take a look at West Wind WebConnect, that makes it possible to send XML from a server to a desktop app, or even an encrypted stream to be DEcrypted at the desktop.
Take a look at Eeva server, which, with some tweaking makes it possible as well.
