I think PG probably knows exactly what Comet is. I also think his question: "aren't all web pages real-time?" was most likely a loaded one.
If I were interviewing you, you bet I'd ask something similar. I'd want to find out if you grasp the implications of using Comet as your company's technical backbone.
Yes, or he misunderstood the question about real-time. If PG doesn't know about Comet, he surely knows about Ajax, and so he surely is aware on how most web pages aren't real-time.
