Sorry, but I find this approach very rude to your customers. It's kinda your job to make it work on your side and don't transfer the burdens to clients.

I don't know what your SAAS does (maybe it's not really applicable here), but in the case of github, it's very wastefull. Yes, it would take some work, some servers, etc but they have the skill, the money and everything they need to do it. They could do it once (well, with every change, but it's not very often) on their side instead every client on every pageview will have to do the same work again and again, wasting time and energy.

Interesting point of view, but I feel you're missing the point.

Do you find all native applications rude to customers?

[muhehe]

No. I'm absolutely expecting local native app to do all the work, it makes sense. With SAAS running in the browser I expect all the heavy lifting is done somewhere else...you know, as a service.
