Hello List: My Grandson on the East Coast wants to see and chat via our Computers. What is the suggested Hardware and Software. Grandson has a PC. My Set-up: PowerMac G4 800 Dual 1.25 gHTZ, with OS 10.4.10 with Verizon DSL Would I be better off getting a USB 2.0 PCI Card, and which one. Or using Firewire? Thanks for input and suggestions. John
