Based on a blog post at Google Blogoscoped, it looks like Google's in the process of inserting Google Gears into Google Apps. This will allow users to work with Google documents offline, rather than always having to be connected to the Internet.
This development is of interest to me because I'm in the process of updating my Google Apps report. Although it came out only five months ago--a short time ago for a report on software applications--it's now out of date, due to Google's continual updates. Google now has Presentations, the company is hinting that JotSpot functionality will finally turn up, Gmail now supports IMAP, etc. While I think Google Apps, Premier Edition still has a way to go before large enterprises will buy it, Google is clearly going down the list of prospect objections and picking them off one by one.
