I tried TokBox this weekend as a plugin for my WP site and once the participants were able to log in we experienced a terribly long audio delay (about 5 seconds). We had to implement radio-talk signals ("over") so as not to interrupt each other.
Otherwise the video transmission was OK. Granted, we were both on wireless signals, but isn't this how most communication is done nowadays? Anyone has any ideas if this can be boosted from the server side? I'm on a shared plan on Hostmonster.
I am considering trying to implement an OpenTok API solution to a new project but if this works like it did with the WP Plugin then I think I'm going to have to look for other solutions.
