Alternatives to ISDN postscript

Although iSpeek isn't out yet, and although it has been in beta-test within the U.S. for some time now, Frank tells me he tried it for the first time today with a European client! And that latency was on the order of 50 ms!! That's better than ISDN! The session was to record a perfume commercial that will air on Italian television soon. I would call that the sweet smell of success. Can't wait to try iSpeek...
