It could create a whole new architecture for software - just the patented parts hosted remotely in software-patent-free zones while the rest is brought local to the customer. At least for the types of products where that works.

Sounds like contributory infringement to me. Why not just host the entire thing distally and access via VPN?
The answer lies in where a product is considered to be sold. If you're targeting customers in the USA say then it doesn't matter where your server is you're still considered to be selling in the USA.
YMMV and I'm afraid I don't have any caselaw handy to cite on this.
