Phone Calls via Google Talk, Offline Google Docs. I’ll be even more stoked if the GTalk service lets you conference in with multiple people — even just 4 or five total would be great. I’ve been using the Google Spreadsheets for awhile and just had a chance to work on Google Docs as well — they’re good products, though copy-pasting back and forth between that and Word, working on the document in both programs several times each, proved to be a recipe for pain. Still, for a beta product, it’s awesome.
