Since there's bunch of instant messaging softwares out there... (including iChat too!) and now many VRS offer ip relay via IM like AIM... and I realized that I do not need VP software or hardware to make a peer to peer (or point to point) calls since the broadband internet is sufficient enough to initiate a videochat with one other! (I realized this after Z4 was launched last monday and it provided similar functions to iChat: 3 way chat, video recording, presentation, text or video relay, etc! and I am like why am I clamoring to get Z4 when I already have those features on iChat! sheesh! )
And nowaday, many can add a mini computer like Mac mini, Dell Inspirion Zino HD or other computer that is in compact size and add webcam like iSight or such then can start videochat from couch like we can do with VP.

Or buy a 27" iMac and turn it into a media center and communication center!

You see HOVRS discontinued distributing MVP because they focused on P3 and P3 Netbook meaning $ sales for them while MVP were free. They will continue to support MVP.
(source: HOVRS - FAQ
ZVRS don't give away their VP for free and wants $ (of course at discount for dhh and full price for hearing) but give way free Z4 for your pc or mac.
I have not used my VP (I have VP 200, MVP and d-link) much lately because I have iChat on my iMac and I have IM/Text on iPhone (can make text relay call on it!)
(Of course, I would use MVP when I am out of home for portable use but it will left out when I buy a macbook!)
