Plaxo to Sell Address Information?

From a story this morning on Plaxo:

In the future, more partnerships could be added by linking to the company’s application programming interfaces (APIs). By using Plaxo’s APIs, an e-commerce site could, hypothetically, automatically retrieve an address for the intended recipient of a gift, Masonis said.

Ah, so Plaxo thinks they’re the center of the identity universe after all!
