Oh yes, when I said a "half day of tinkering time" for wireless set up, I don't mean anything excessively technical, or only for the ability of a professional. Setting up a wireless network is extremely easy now, although you should purchase one of the PCWorld Mags or equivalent on the subject and read a bit before making a purchase and setting up a system. Basically, a beginner can set up a wireless system in a very short time. But establishing a rendering system across your network with a product like Vue's Rendercow takes some tinkering. This is true, regardless of whether the network is wired or wireless. But for those upgrading their systems simply to get faster rendering times for Vue or Vue Pro, the cheapest, smartest, best thing that you can do is to buy a new (known to be stable) motherboard-cpu-ram rig that is one step back from the impending or current bleeding edge, buy wireless equipment, and lash your old and new stuff together via wireless. You will save something on the order of $1000 USD, doing so, and have a good system to carry you for about two years - into the time when the new PCI and cpu technologies are cheap and commonplace.
