VNC - link utilization

[Caseiro, Bruno]

Hello ALL,

	I'm studying to use VNC 4.x (free edition) to manage our workstations that
are placed in some of our branch offices. Does anybody knows how much of
bandwidth VNC uses per connection? For example, if 20 support analysts from
one location needs to manage and support workstations in another location
simultaneously, what kind of link is necessary to support this? (64kb, 128kb,
256kb, etc).
Thanks.
Regards
Bruno
