In Risks Digest 20.80, there is a review of "Virtual Private Networking"
by Bruce Perlmutter/Jonathan Zarkower. The third paragraph of this
review contains this:

"(I would note that the authors suggest cable modems and Digital
Subscriber Line [DSL] technologies can be used in conjunction with
VPNs in order to create a high speed connection between offices. It
should be pointed out that both cable systems and the most common
form of DSL have an inherent asymmetry of bandwidth that prevents this
usage.)"

I am aware of the different upload/download speeds on DSL lines. But I
see no reason why this would prevent a link. Surely the link would
merely be at the slower (upload) speed. Is the reviewer ("Rob Slade"
<rslade@sprint.ca>) wrong?

cheers
