Skype really saved my hiney last week while I was in Copenhagen. It could always tunnel through whatever network I was hung off on, and the reception back to the States was pretty good. I'm absolutely sold.
Now I want "SkypeIn". No, it doesn't exist yet, and I still want it. I want to be able to forward any of my phone numbers to my Skype number, and have it ring on the PC where I have Skype running. That's a service I would pay for. I would love to have my office number forwarded to it, my cell forwarded to it, my distinctive ring number at home forwarded to it - the ultimate answering machine.
I know that Vonage offers this service, and Vonage sucks more than Dyson vacuums.
