I'm having a hard time differentiating between the normal bs of the whole 2.0-ish way the blogosphere is talking as of late. I want to put on paper (err... e-paper) what VoIP 2.0 is. I'd really appreciate your input here.

VoIP 2.0 is:

• e911 (vonage)
• video (Skype 2.0)
• blog integration (Skype 2.0)
• social (SkypeMe)
• instant messaging on-board (gizmo, Skype)
• mobile (IPDrum, Iotum, SoftGnome, SkypeIN/SkypeOut)
• for business and PBX (all?)
• for home (all?)
• for podcasts (Skype, Gizmo, ConferenceCall.com)
• open (Skype, Gizmo)
• stable/dependable (opinions wanted here)
• cheap (PhoneGnome)
• easy enough for grandma (PhoneGnome)
• smart (Iotum)

Any more?
