MSN Enterprise Search?

I'm not sure why this raises my eyebrows, but Mary Jo Foley is reporting that MS has an enterprise version of their desktop search product in the works. I'm guessing this will compete with the Google Search Appliance.

I wonder if this will be a way for Microsoft to undercut Google like they did with Netscape. Perhaps they will release their Enterprise Desktop Search (or whatever they'll call it) for free. Where does that leave Google? Microsoft learned the first time that "free" beats "superior technology" in the technology RoShamBo.
