You guys/gals will be pleased to know I still run some Win 95 and NT4.0 boxes! All off network though. Also got some OS2/Warp 4 machines scattered around the place (ATM's)!
hey mad_jock, apple stuff can be noisy on networks, but some of their networking stuff is pretty neat. Bonjour is excellent, likewise the spin off GNU stuff (avahi) is also pretty good. I am no network engineer, but I work with some and they do constantly have challenges with it on large networks with multiple subnets. It also makes up for a large amount of network bandwidth when you have a lot of devices. Its becoming a real problem with things like iPads. However, like you said, if you can segregate it to a small subnet then it really is a good thing. Mobs like cisco and motorola are doing grand things in this space now from what I have been told.
