OK. Now I'm very curious about the move to Guacamole. Citrix ICA is the fastest remote desktop protocol around. Even a very seasoned VMware engineer I work with will only deploy Citrix for VDI that requires low latency and quick response times, as he admits that VMware's Blast protocol is not battle proven. So you are saying that Guacamole delivers better performance than Citrix. I guess I will have to try it for myself.

Huh, I'm very curious what it is you're doing.

On the one hand I immediately think of CAD, but that hates remote desktop solutions.

The only thing left is mass client simulation/networking simulation, but you just said virtualization won't work for your use case.
