Office Web Application
I have heard about this not long ago but have to keep quiet until now. Office Web Application is basically web based Office applications hosted on the web. It is based on a S+S model powered by AJAX and Silverlight. It is available on Office Live (for consumers) and as volume license (for enterprises) In near future any devices (incl PC and phones) will be above to open (and EDIT) Office documents on the web! Best of all, Office Web Application will ship with Office 14!
There is a screencast here on Channel 9. And Joel Olson is blogging about it too.
