As anyone who reads what I write here probably knows, I've spent the last 2 weeks in China, in two different offices in Beijing and one on Shanghai.
Some months back I installed Sun Ray server on my workstation in Sydney (as I prefer to run on relatively current nevada builds, rather than the Solaris 10 builds that IT Ops provides) and moved over to using a Sun Ray appliance both on my desk and at home.
I've been very happy with the ease of use of being able to transfer my work session home.
I've been even more happy with being able to transfer it to the various offices in China!
I just put my card in, it throws me to the Sydney ITops server that I would normally connect to, and I just utswitch from there to my own server. It all just works. What's more I've found working from Beijing very little different speedwise to working from home. It's all quite usable.
