No, WinXP64 does nothing for Vue, yes, only if it's written in 64-bit. Of course, you'll need a 64-bit processor. Buy the router, it'll act as both a firewall and a DHCP server. A hub is a simple switch allowing more than one computer to access a shared resource. It won't issue your needed IP Addresses to multiple computers like the router will. Your gateway router will take the IP Address issued by your ISP from your DSL or cable modem; your gateway router will dynamically issue static IP Addresses to the machines/devices on your network (192.168.0.2...192.168.0.3...192.168.0.4 etc.). Of course, you'll have to know how to set up a network, which is fairly easy; just avoid mixing operating systems to make the setup easier if you're a novice. Stick with XP Pro or Home. Yes, you can use one monitor. Buy a KVM switch. With the KVM switch you'll need just one monitor, keyboard and mouse for your three or more machines. KVM switches are made by various manufacturers; stop by your local computer store. Ask about routers as well. A fairly decent 5-port KVM switch will cost $100 or a little more. A decent gateway router with a decent firewall will cost $89. Consider LinkSys or Netgear. The beefier the firewall, the more expensive the router. And don't forget to secure your network if you're going wireless. EDIT: Make certain your KVM switch handles both USB AND PS/2. Not necessary, but it makes life easier.
