This is funny: Microsoft ploy to block Sun exposed - Tech News - CNET.com. Microsoft has a project codenamed 'foo'.

An attorney representing the nine litigating states and the District of Columbia read portions of Gates' e-mail, concerning a project code-named foo, during last Tuesday's cross-examination of Microsoft Senior Vice President Jim Allchin.

During the cross-examination, Allchin said he was "not 100 percent sure" that Gates was referring to the WS-I. But in a February deposition, Microsoft CEO Steve Ballmer said the term "foo" was used internally at Microsoft to refer to the WS-I before the organization was officially founded. Sources familiar with the e-mails also said the term foo was used at Microsoft to refer to the WS-I.
