>> "Is there a way to extract any information about product name/version from the license key without actually activating it?"
Nope, not currently.
In the near-ish future (no hard date) we're adding a client portal for customers to manage their licenses. They'll just be able to add the license and "magically" get all the information about it.
You can always use the web API via a script on your website to query information about product keys. More information is needed about what you're trying to do in order to give you useful information.
