What about the idea of going BEYOND OWA....picture this scenario.
A corporate user is out in the boondocks, with a slow bandwidth connection. He needs to work on a 15 meg excel document due in 25 minutes, just a few changes. However, if he was going to log into OWA, he would have to download the attachment, and work on it. Now how about this-->
He logs into WO 2008. Web Outlook 2008.
Once logging in with domain credentials via https, either a java applet, or some other spiffy HTML coding, shows the full outlook client in a window, not the bone dry OWA that isnt as fully featured as outlook. Joe Blow logs in, and the only data he downloaded were the pixels to represent the screen. Say he sees the attachment, he can right click the attachment, and operate on the excel document in the full excel application, but the application is shown to him as pixels, a virtual work environment. All data changes are maintained on the server, without any downloading any of the core document data. Once he is done working on the document in the VE 2008 Environment (Virtual Excel), the attachment in his inbox is saved to a "worked on/saved" subfolder in his inbox, then ready to be sent to target destination, where no uploading is involved because the data is on the same lan segment most likely as the mail server, while joe blow is 4,000 miles away. This could be pricey, but I'm sure there are thousands of enterprises that would love this full functionality, to put a nail in the coffin of Googles web based offerings. FULLY FEATURED, with nothing skimped.
This would be a godsend for our corporation, it may require slightly more bandwidth then a dialup connection, because in this day and age, if you aren't on land-line broadband, you're easily leeching someones broadband wifi. . .
What do you all think?
