From time to time I get reports from users that say they're using some software that prevents the browser from loading script code from other domains.

I don't know where it's written that thou must only include code from the same domain. I re-use components in my web apps. Each app has its own domain. I don't see why I should have to maintain copies of identical files in different folders to make some weird software happy.

Further wasn't this the basis for JSONP? The idea that if you wrap data in script code you can reference it anywhere?

I'm not even sure who writes this code, or what the name of the software is. The bug reports from users generally don't include this info.

It also doesn't happen that often.
