What I was referring to (unclearly it seems), is that if the software
in use does not change the screen much/very often, then the clients
will catch up - it just takes longer over a slow link. If the screen
image is much more dynamic, then the bandwidth requirements will go
up - and if there isn't enough bandwidth, then the clients will
simply not get all the updates.
One way to improve the perceived performance is to reduce the
quantity of screen image changes that have to be transmitted - by
removing unneccessary things like animated slide transitions in
PowerPoint, or fancy background images (that have to be retransmitted
when they are uncovered etc.
