1.	There are two sides to search -- crawling and queries. We now have a partial interface to the query side of search. An obvious next step is to complete the interface. But to really get the benefit of the connection between content management and search, the other side must have an API as well. When a website updates, it should be able to ping the search engine, saying "I just updated." The crawler doesn't have to believe the ping, it can verify for itself that the site has changed. And if, for some reason, its policies say that the site isn't one that the search engine considers important, it can ignore the ping.
2.	Today Google has a two-day turnaround for fast-changing sites. It seems that with a simple SOAP interface for update notification, for which there is prior art, the two-day turnaround could become an hour or less. The benefit is that Google's index would become more current, more just-in-time, more competitive, more valuable.
3.	Also, put a pricetag on the service asap. $15 per year per user, for a maximum of 1000 queries per day. Instead of disallowing commercial apps, become one. Make money. This is essential if Google and its nascent developer community are to grow and survive to do more cool stuff with the Internet.
