This feature has been implemented and is available in the dev/2.2
evolving pre-release build:
http://www.turbovnc.org/DeveloperInfo/PreReleases
(Mac build is still hung up in the Travis queue but should be available
shortly)
Feedback is appreciated. This is similar in concept to the multi-screen
SourceForge removed the ability for project admins to view/manage the
members of mailing lists, which was the final straw. Given that there
is some cross-pollination between our projects and TigerVNC, and
TigerVNC is using Google Groups, I decided to do likewise with both
VirtualGL and TurboVNC.
