Problem is, there's no one good way to do it.
Kidaro offers end-user management and security advantages but doesn't guarantee overnight scalability to 10,000 users, the way Citrix's user application virtualization product, Presentation Server, does.
Pano Logic invites its customers to leave PC hardware behind altogether and adopt its 3.5-inch square chrome box. The Pano offers the advantage of relaying the user interface from a central server to a desktop display with minimal hardware expense, but you won't necessarily find a shiny Pano box in every hotel room.
XDS offers the hardest-to-explain option, which consists of authenticating end users on a remote server at an XDS data center, then equipping their desktops with virtual machines from a server inside the user's data center. The approach offers advantages in security and provisioning large numbers of users. But the company's explanation has left many scratching their heads on how to adopt it.
Totally agree, but I am going for that little appliance called Pano Logic. Trust me a lot of folks I have been speaking to, are convinced that the future of desktop is to have as little work on the client side and more data storage on the server. Obviously there are heterogeneous scenarios and they will not go away soon, but still I would rather go for a Pano Logic kind of solution than all those bulky and temp fix solutions that most vendors have to offer.
