fundamentally, all those native apps on other platform are linux apps, is it possible to write a application layer like wine? such that the android and iPhone apps can be easily wrapped and work on the webOS?
Just a thought. since right now hardware accelerated apps is easily possible on webOS.
It would be [i]possible[/i]--time consuming, but possible--to emulate Android system calls with Java services on the Pre. Basically, unless a company wants to market this as a commercial product, the time required would be too much.
As for the iPhone... it is BSD-based, which is completely different from Linux architecturally. Also, the apps are written in Objective-C with Cocoa libraries. The former is portable, but the latter is copyrighted by Apple AFAIK. Again, it would theoretically be possible, but the potential legal troubles make it unfit for a commercial app, and the task is way too daunting to undertake as homebrew.
Of the two, Android is definitely the more likely. However, I doubt we'll see this any time soon.
