Google Packages

I noticed that there are a number of Google Related packages springing up lately... Are these at all related to each other (from a development standpoint) ? The main reason I ask is because I was thinking of implimenting an Adwords/AdSense package before noticing one was already in the pipeline. Could these packages benefit from a common base ? Slightly off topic, I also think the naming of the packages is a bit akward: Services_Google -> google's search API Service_GoogleSiteMap -> google's sitemap [protocol] API Services_Google_Adwords -> Adwords API wrapper On a sidenote, I am very interested to help with the development of these packages, especially the Adwords one, if the developers are out there...
