I'm in Canada, and I'll tell you for certain that whenever the cloud is mentioned in business it is often followed by the assumption that "all your personal data - or worse, your client's data - will be subject to the PATRIOT act". It's a huge killer to accessing many of the cloud services that are available for US companies for anything requiring some sort of security.

To be clear I don't hang at the local campus - this is suit and tie businessmen and women that I'm talking about here, not the tinfoil hat crowd.

There's huge opportunity for setting up cloud services for countries outside of the US right now, simply because of this little issue.
