Is there a Citrix like option for Macs
 

No one has answered whether there is or is not a comparable Citrix like app for Macs. I am looking to have multiple Mac users log into the network and create Terminal Service Sessions via the server or anything. However, it needs to be screen refreshes--this is what Citrix does--so that it doesn't cost much in bandwith, like many mutiple VPN logged in at the same time.

Anyone have any solutions?
