vWorkspace 7.5 and powershell and infrastructure setup

    Is the new vWorkspace powershell tool compatible with 7.5?  Also we will have about 300-400 users accessing the new environment, currently I have 2 connection brokers, 1 web access\secure IT server, and a seperate SQL server and these are all virtual machines running in vSpehere 5.  Just seeing how other people are configuring their infrastructure.
