Also take a look at what Loki has done on http://www.geocaching.com/.   
They use content to explain to the user that (a) they need to install  
loki, and (b) it is how it is going to be used.

http://brightkite.com/ also uses content to explain to the user that  
its is going to use geolocation to update there position.

Both are great solutions not requiring that you blur the line between  
the trusted browser UI and webcontent.
