Clients and appliances within the same SDP version are always compatible - so a 6.0.5 Client and 6.0.1 appliance would be fully compatible. Client backwards compatibility is guaranteed for (at least) two SDP versions, so a 6.2 Client would work against a 6.0 server.
FOR WINDOWS:
Full, Headless, Always-on, Multi-user and SSO/PLAP all use the same Client installer. Lite Clients have a separate installer. The installers require PowerShell to use install-time options.
