Lobo- Apologies for the delays you have experienced. Good news is that yes, Xenith 1.6 is now officially released and available to all customers on maintenance (not that with Wyse maintenance is not only includes bug fixes but full feature releases as well). You should be able to download it from the self-service site.
Additionally, the following document currently still in draft (but expect a KB article) should help you with the setup on the CAG side: http://www.box.net/shared/static/7ka...yc4lpj9ma.docx
But I'm not using Netscaler. Is there any documentation for connecting to just CAG 5.0.2? Nothing in this document even resembles the setup of CAG
