Citrix have released version 8 of their firmware for the Access Gateway Enterprise Edition (that's the version that runs on the same hardware as the NetScaler appliance family).
This version is the first (of the Enterprise edition software) to provide the full ICA proxy capabilities we've seen in Citrix Secure Gateway and more recently in Citrix Access Gateway appliances. Essentially it means that users can login and access Presentation Server-based applications without have to establish any VPN connections. The ICA protocol is simply tunneled within an HTTPS connection and reverse proxied by the Access Gateway.
The key difference between the Advanced and Enterprise version of the Access Gateway relates to the number of concurrent users you can support. The standard CAG hardware (2000 series) can host up to 2,000 concurrent connections. The Enterprise platform increases that number to around 10,000.
