Is there a data usage monitoring app that shows actual stats from the carrier?

Now that Verizon has unveiled its shared data plans, an app that is able to periodically check your carrier's server for your account's total data usage would make a lot of sense, rather than just an app that tracks usage on your device itself.

Are there any apps like this that already exist? Is an app like this even feasible (that can use your Verizon/AT&T/etc. account login details to check their server for data usage?)
