Was Plame, in fact, undercover when she was outed?

Novak says the C.I.A. told him"the exposure of her name might cause 'difficulties' if she travels abroad," but that"[i]t was well-known around Washington that Wilson's wife worked for the C.I.A. . . . Her name, Valerie Plame, was no secret either, appearing in Wilson's Who Who's in America entry."

Hitchens sneers that she"shuttle[d] dangerously 'undercover' between Georgetown and Virginia."

Clifford May lets slip that he knew her name and identity before Novak’s column outing her: “I learned it from someone who formerly worked in the government and he mentioned it in an offhand manner, leading me to infer it was something that insiders were well aware of.”

On the other hand, Tim Noah uses a"simple test: did her friends and neighbors know she worked for the C.I.A.? They did not. Ergo, she was undercover."

Postscript (7/21/05): From this week's Time magazine:

[A]s recently as the late 1990s she was working as a nonofficial cover (NOC) officer, one of a select group of operatives within the CIA who are placed in neutral-seeming environments abroad and collect secrets, knowing that the U.S. government will disavow any connection with them should they be caught. NOC officers cost millions of dollars to train and support. As a result of the leak, Plame is no longer able to work undercover. [link]

[W]hile she may no longer have been a clandestine operative [at the time of the leak], she was still under protected status. . . . In the wake of the disclosure, foreign intelligence services were known to have retraced her steps and contacts to discover more about how the CIA operates in their countries. [link]

Postscript (7/24/05): From the NYT:

[Some] former C.I.A. officers say that by 2003 Ms. Wilson's cover was already thin. Any serious inquiry would have revealed that Brewster Jennings [& Associates, the shell company in Boston the C.I.A. setup] was little more than a mailbox. . . . Ms. Wilson . . . had been working for some time at agency headquarters in Langley, Va. And her marriage to a senior American diplomat, Mr. Wilson, ended any pretense of having no government ties.

"At that point, she looks, walks and quacks like an overt agency employee," said Fred Rustmann, a C.I.A. officer from 1966 to 1990, who supervised Ms. Wilson early in her career and calls her"one of the best, an excellent officer."
