With all of the Apps that Googles library has to offer, none have the customization and ease of use you find with Teamdesk. My suggestion is that Teamdesk offer its application through googles apps marketplace and integrate Google Doc's, Google Calendar and Gmail with Teamdesk. I already use Google Apps for my Company Website and take full advantage of the RSS Feeds i create in Teamdesk by creating a website for each of my clients I control the flow of information from Teamdesk into their sites to ensure they get the information I want them to have in a constantly updated and live environment. It seems like it would be a natural fit to have the programs integrated and I think alot of your users would be pleased to have the ability to integrate some of the google applications they already use with teamdesk. I also believe Teamdesk would benefit from the exposure of offering the application on the Google Apps Marketplace and open itself up to a whole new segment of potential customers.
