Precisely, Don.  With your suggestion of using VPNs to keep LTSP and
existing school district PCs logically separate, we are looking at
replacing at least some of our switches, the Matrox ones, which don't
support 802.1q.  There are not too many of these, most of the rest are
Cisco 1548Ms, and if they do support 802.1q, then we'd likely replace the
Matrox switches with Cisco units, even if a bit pricier, since all of our
routers are also Cisco units.  If we have to replace all classroom
switches, then we'll search out the most cost effective solution.  And if
the cabling is Cat5e, then we'll look at gigabit capability as well for the
new switches, as you surmised.

We meet with district IT personnel in a few weeks, it will be interesting
to hear their take on the VPN proposal, as well as the whole Linux
business.  While our school is doing this for performance and reliability,
most of the district, which is currently hurting for technology funding,
would also benefit from the cost savings aspect...wish us luck!

Daniel
