I stumbled on this from my cousins in Australia....
We can talk (ie with our voices!)directly through our computers with a free account at Skype and a microphone on our computer. FREE! They also have services that let you dial from your computer to an ordinary phone for cheapo dollars anywhere in the world but I just use the computer to computer service. It would be a great way to keep up with fellow cat sailers who have wireless computers especially. The address is www.skype.com and you have to download the program.

You mean I have to talk to Wouter for real now!?!
Just kidding buddy!
HA! 
Everything in life has pluses and minuses.........
I think in Wouters case it would be more accurate to say, "You mean I have to LISTEN to Wouter for real now..."
Skype is brill; I've been using it for a while now - saves on the international phone bill
I'll keep an eye on Google talk, but sticking with Skype for now
skype is apparently not doing so well financially
