Shred I support the notion of a web service from Vodacom!
That's what I'd like
Simple username-password combo, or even for added security if they can pair up the originating connection with an account.
Simply returns basic "how much left", or if required more verbose information.
Total-Left-Expirydate for all the active 'bundles'.
All you need, and you can do all kinds of funky with it
