Bing.  With the dayjob hat of a high speed access provider, we get no 
end of issues on everything from end-users not "getting their full speed"
due to loacl or remote using 802.11b or lousy TCP implementations (untuned 
win98) or the like.  These occur just as often as remote hosts on a DS1
or swamped 10M access, etc.

This also bears repeating.  The investment community's timescale is 
dramatically different than that of the decisionmakers for capital 
spending in most companies.
