Videophones Revisited, by Way of the Modem [NYT]: David Pogue takes a look at a desktop DSL-based videophone that uses the H.263 protocol. Limited install base, as with the iSight, means limited utility. Again, like iSight, the phone uses a standard and can theoretically link up with inputs from alternative video-chat sources.

(Note that the link is to a co-sponsored archive for the article, preventing traditional NYT linkrot. See here. Spotted on MeTa the other day, which looks to be downt agin.)

Jeff Carlson at TidBITS also looks at iSight and iChat AV in a bit more depth this week with a passel of tips and tricks from his book on the topic.
