Ok, I have some friends who have justed move to the UK for a year. I couldn't convince them to pony up the extra for an iBook so they have a new low end Dell with XP. So, I want to help them set up video chat with their Australian relos (windows users) and hopefully figure out a video solution for me on my mac. Help? Whats the best XP to XP solution? Is there a OSX to XP solution?
