- if it's a "thick" app, where do I store it?
- if it's a web app, where do I host it?
I suppose there are also browser add-ins, they'd have the same issue as thick apps.
Some web apps can be run on Google App Engine, I suppose. Or I could fire up an EC2 image. How do I pay for the EC2 usage? Maybe that's step 2 after I get something that people like.
