Which levels? You can certainly serve true randomness sufficient to seed cryptographically secure PRNG generators. Right now all my VMs and systems at home are served that from a good source of true randomness. I've seen such sources on the net, e.g. http://www.random.org/ http://www.random.org/ The big issue is trust, especially when it's relatively easy and cheap to provide true randomness locally. And as mentioned, a standard desktop can generate its own randomness through things like mouse movements, which is very cheap. The major use case would be VMs, and I suspect few who run them would trust an external source, unless their cloud vendor offered it as a service. I could see vendors being reluctant to do so for liability reasons.
