Citrix president and CEO Mark Templeton told iTWire that the original beta was limited to Germany, and that selected customers were involved in a private beta in the first quarter that did reveal some areas that needed further optimisation or improvement.
The company learned a lot about the compatibility of various cameras during the beta, and recent hardware changes by Apple were another issue that had to be addressed.
"We are a little behind," conceded Mr Templeton, explaining that it was more important to get the product right than to stick to the original schedule.
GoToMeeting with HD Faces allows video conferences with up to six participants. The beta was demonstrated at Synergy 2011 running on a virtual desktop. Company officials explained that compression is used to handle the volume of USB data flowing across the network from the computer's video camera.
Mr Templeton said GoToMeeting was the the number two product in the worldwide web collaboration market.
