Preenv is possible because the similarities of WebOS and Maemo Linux platforms. Android and iOS are completely different.
Still, porting it to Maemo could be easy enough, but if you sell something, you have to provide support for it too (like someone asks the dev, why wont the app run on his N900 when he removed and purged python), or you can make it freeware, but that is quite unrewarding for those few hundred, maybe thousand people they can get this way. I don't say I wouldn't like it, I just say you should take that letter with a grain of salt, like Nokia announcing Flash 10.2 for N900.
