Vista - Expiration Date Technique

Does anybody have any clever technique to implement an expiration date in a
WinForms app, such that it could outsmart any user who tries to change the
system clock to avoid expiration?

If it's just the system clock you want to be able to beat, you can have your
application retrieve the current date from a server via a web service,
rather than the client pc. It would mean that the client would have to have
an Internet connection as a requirement for using your applicaiton, but
that's not as big of a deal as it once was.
