Google announced the Analytics Data Export API some days ago, thereby making it much easier to get analytics data for a site. The API debuted with Java and Javascript client
Check the trunk of Google's .NET library, they have added Analytics support.
Also check their groups post on this:

It's not using the built in library you mention but it's working pretty well. The whole API is XML/HTTP so it's pretty handy to use. You basically ask Google for a webpage and examine the response for what you need.
Google has release a new breed of Apis which are listed at Google Api Explorer, you can see the entry for Google Analytics. And there is a .Net client which provides .dlls for all of these Apis. This is Google so it is still in Beta but I'm developing off it with no issues.
