The eBay Skype Acquisition Smells -- Sweet or Rank?

The eBay Skype acquisition interests me.

I see how a VOIP connection within eBay would be great for buyers and sellers (maybe eBay has more plans, too). But I don't see why they didn't just build the system themselves. Google did it quickly and easily -- which suggests that there's no "moat" around this kind of technology (to borrow a phrase from Warren Buffet and Charlie Munger).

Any thoughts, insights?
