Hi Estera,
I've been thinking a lot about a way of doing remote desktop as a service, to ensure maximum security and availability (via the usual cloud stuff). Essentially it's a way of building a trusted network without the hassles and expense of in-house monitoring and regulation, without losing the benefits of remaining ISO27000 / PCI compliant. Essentially the entire remote desktop architecture could be transformed into a distributed system that allows security to be monitored across a range of endpoints with very little end-user effort.
