Google Wave and Advertising

An interesting topic is how advertising will fit into Google Wave. It would appear that Google Adsense type advertisements would be a good fit for Wave. A Wave robot would be able to carry out an analysis of what was being discussed in the wave and insert appropriate advertisements. This could be done more interactively and at a much finer level of granularity than with an email message, web page or a blog. If well done the advertising should be helpful, rather than obtrusive, rather like the robot being another participant in the conversation.
