Al, your comments sound good in theory but it doesn't work that way. We have Winframe in our office, so I am speaking from experience. Unfortunately keyboard and mouse response is very much delayed if the server cpu is loaded. The delay is so bad that it becomes impossible to point and click accurately with the mouse when some other user is doing something cpu intensive with Excel. Key lag is annoying but can be lived with, mouse lag renders the mouse useless. You can reproduce this effect on any Windows machine, just start a cpu intensive task in one window, then open another app and try moving the mouse around. There is no free lunch. You simply must have enough cpu resources to support each of your simultaneous users. "Fill in the blank" type apps, such as ordering or reservation systems, can serve many users per server. But MS Office97 apps require the resources of a 200mhz equivalent processor and 16meg memory or more per simultaneous user and even with that you can get lag problems if one of the users is a hog. Perhaps this situation is improved with multiple servers and load balancing, I have not tried that. My conclusion is that Winframe is great for large distributed apps that are not cpu intensive but that general office apps should remain on the desktop. Winframe (and Picasso) are for replacing dumb terminal applications, not for general office apps. And the stories of saving on software costs by buying only one copy of office apps and having many users share them is malarky. You must purchase an additional software license for each Winframe user. If you have 10 users for MS Excel, you must purchase 10 licenses whether the users are using it on the desktop or on a remote server. No free lunch here either, just a slight saving on installation time offset by degraded performance.
