I have a student computer lab with 50+ desktops that I want to switch over to virtual desktops. Network bandwidth isn't an issue (we'll be running at least 1gb end-to-end). The goals are:
Get rid of the conventional desktop hardware. It's expensive, requires repair and maintenance, as well as imaging systems like Altaris or Ghost and we no longer want to use that method. We also do not want to re-purpose old machines as thin clients. The idea is to remove as much maintenance and up-keep on the client end as possible.
Maintain a single desktop image that can be published for all students to use without the need for student interaction of any type at the client end. In other words, all we want is a monitor, keyboard, and mouse at each lab station connected to a device that boots directly to a login screen for a virtual desktop. The student logs in, group policies for things like Desktop and My Docs redirection apply.
I don't want to maintain dozens of VMs on the backend like I would need to do with XenDesktop.
If you have experience with any solutions that meet that criteria, please let me know. Right now I am looking at XenApp published desktop / apps in conjunction with NComputing devices on the client-side.
