We have just posted an update to the Tech Note that outlines Sametime support for Citrix.
I know many of you have asked us to support more features on Citrix. We have a technical approach to resolving the outstanding technical issues that prevent us from providing full support and we are working on establishing a timeline for availability.
We're making progress in the meantime and this update is particularly significant. First, we now support Citrix XenApp 6.5. Secondly, we have documented a series of workarounds that help improve the Sametime experience on Citrix XenApp including screen sharing through the Sametime Web Meetings Client and screen capture on the Sametime Web Chat Client.
The updated Tech Note is available here.
