If you use PeerGuardian 2 (PG2) and Logitech Vid, you will notice that PG2 blocks NebuAd, Inc at 66.151.151.20:5062. It turns out that this IP address actually belongs to SightSpeed, Inc. Logitech bought SightSpeed on Oct 29, 2008. Because of the nature of the videoconferencing service provided by SightSpeed, one can see that it is necessary for the workstation to check in with a SightSpeed server on a regular basis in order to be able to answer in incoming video call. That’s because most firewalls are configured to block incoming protocols and ports except responses to outgoing http, https, ftp, etc requests.
So far I can’t see an advantage of Vid over Skype.
If anyone knows why PG2 would associate NebuAd (now defunct) with SightSpeed, please leave a comment.
Also, If you see any significant advantage of SightSpeed/”Logitech Vid” over Skype, please leave a comment.
Greg, Thanks for this info, it has been driving me nuts trying to figure out what was trying to get through Peer Block since NebuAd has been defunct for a while now.
