I also subscribe to 8x8 for unlimited long distance in the United States and Canada including all local calls, call waiting, voice mail and all digital services for $19.95 per month.
I would love to see Skype enter the business in competition to Vonage and 8x8. I would switch to Skype in a heartbeat not because I am dissatisfied with 8x8 but simply because I love Skype.
I am sure that is is on your agenda and I can't wait.
In addition, I would like to see Google purchase Skype and implement it in their rumored IM client or I would like to see Skype include support for AIM,ICQ and MSN Messenger in the Skype client so I could remove these programs from my computer. Every program such as Gaim, Jabber, Trillian et al seems to have random problems. I trust Skype to do it right.
