well sure. one of the other reasons I got to pondering the original question ( are we overselling the value of bandwidth? ) is the following: http://newsroom.cisco.com/dlls/video_audio_archive/?video check out the long reach ethernet presentation, maybe 3/4 down the page. LRE can provide up to 5 megabits full duplex over cat 3 phone wire - data and voice. after viewing the presentation, you tell me - is this not saying that 5 megabits is more than adequate for voice, video, etc? as for wireless - I fully understand that the requirements of the application drive the need for bandwidth. I'm just asking - if people are more productive, despite the obvious lack of bandwidth, and despite the step back to a contention medium, is there something to be said about the perceived need for 100 megabits to the desktop? > > Thanks, > > Zsombor > > "Chuck Whose Road is Ever Shorte wrote: > > > > ""Howard C.
