wasnt ohphone compatible with MSN messenger's video conferencing at one point?
from macupdate
"ohphoneX is a Cocoa wrapper for ohphone. ohphone, part of OpenH323 project, is a command line program that does H.323 conferencing. The binary version of ohphoneX also comes with a pre-compiled ohphone. You don't need to install PWLib and OpenH323 before using this application. ohphoneX is targeted as a simple Mac-to-Mac and Mac-to-Phone voice only communication tool, some features will not be provided, but will be included in another application. It provides Mac-to-Mac, Mac-to-PC (NetMeeting and GnomeMeeting compatible) audio communication, as well as Mac-to-Phone through Internet telephony providers that allow you access their H.323 call gateway."
MSN used to use netmeeting (which ohphone supports) for that stuff i thought. maybe it still does...just hides it better. dunno. i dont keep up with msn because its crap.
why not just have your PeeCee friends get Skype? its free and has really good quality video/audio...but is a bit of a cpu hog. they could also get AIM for AIM to iChat, but overall to me Skype is much easier for cross platform video conferencing.
