I do really enjoy it as a way to put some random windows app like IE so Linux clients can run it in seamless "portal" mode. It's easier for users to understand than traditional rdp. However I have had issues with people who use it all day every day. Seamless rdp is just buggy. Unity has no idea what is going on with it when used in multi window applications and that can confuse users when they switch between windows. I ended up having these few users just use plain rdp. The people who use it once in a blue moon seem to love it though for the convenience. Ulteo also has a full desktop mode but I don't use it and can't comment. I also don't use Ulteo for Linux applications but it can be used for such. I don't think it's possible to pxe boot directly into a Ulteo desktop environment. You have to use a web portal. ''''Proxmox'''' - This is my preferred solution for server virtualization. It's a gui for KVM and openvz. I minimally trained sys admin can set up a new VM in minutes with it. I have had times where the GUI doesn't work and I had to use CLI. Still I like it better than pure CLI. I also found the upgrade to 2.x unpleasant. ''''LTSP'''' - Have you considered this? It's not virtualization it's just multi user Linux. I use it in a computer lab type scenario. I've posted about it http://davidmburke.com/2012/02/26/computer-lab-on-the-cheap/ The issues it has (video processing, external devices are hit or miss) are likely going to be issues with any solution for desktop virtualization. I am also a fool and don't use a server with a decent GPU made for this sort of thing. If you need windows apps I suppose you could use seamless RDP or Ulteo in your LTSP image but I have never tried this. In terms of cheapness LTSP is hard to beat. It's very easy to maintain. Need a new application for all clients? apt-get install on the server. Done. Clients don't have to reboot or anything (maybe they would if they were fat clients?). Initial setup isn't bad either.

Citrix XenDesktop/XenApp
Citrix virtualization solutions are popular on the market. Being backed by open-source Xen solution they may be considered as a viable option to use for applications you cannot use directly on your desktop.
The Citrix Receiver is missing some features and has a number of bugs (November 2012). Here is a guide to deploy the Receiver to Ubuntu machines:

VMware View
RedHat VDI
Remote Desktop with RDP and VNC
Providing Ubuntu apps to Windows users
I think the above would mostly be used for accessing Windows applications. However, some use cases suggest going the other way round or using Linux apps remotely from Linux. Provisioning of Linux apps comes here
