iChat AV you + X requirements clarification

[stoid]

For those of you that have Tiger, I was wondering if we could clear up the requirements for three-way video chats and such.

My situation is wanting to do a three way video chat with these machines:
PowerBook Aluminum 1.25 Ghz
PowerBook Titanium 867 Mhz
iBook G4 1.2 Ghz


I know that it officially says you need a G5 or dual 1.0+ G4 for the four way, but I was wondering if the machines I listed could handle a three way.

Woah I didn't realize that had different reqs than the operating system.

To HOST, you will need a dual 1ghz G4 or any G5. To participate, u'll need at least a single ghz G4 or dual 800mhz G4. These are the requirements for 3 or 4 way video chat.

For single 1 on 1 video, requirements are same as before.

So it's the same for 3 way as for 4 way? Do you start the chat differently for 1 to 1 than to a 3 way? Seems rather silly that they wouldn't have lower specs for a 3 way as opposed to a 4 way.

Do you know that the 3 way is just as high from experience/know someone that has tried, or are you just guessing like me?

h.264 requires a lot of processing power to encode/decode stuff. it's very efficient, but very intensive to encode.

Does anyone actually know, from experience, the answer to this? Has anyone tried and failed to initiate a 3- or 4-way iChat AV video chat on a Mac with a G4 at 1.5 GHz or thereabouts?

Is this a 'soft' recommendation, below which iChat AV will perform poorly, but work, or a 'hard' one where the software tries to detect the hardware specs and in certain cases won't let it start or something ...

I can't get a 1GHz Powerbook G4 to participate in 3 or 4-person video conferencing in iChat AV 3. The initiating computer is a Mac Pro, and all 3 Macs have 10.4.8. Could it be that the Powerbook can't participate because of low RAM (256MB)? RAM is not listed as a requirement on the iChat AV page. Any help would be appreciated.
