I can't talk about the details of the iPhone's hardware but I can tell  
you that iPhone and iPod touch do not have room for significantly more  
runtime memory use or code footprint. Getting WebKit (pretty small for  
a browser engine) to run was hardly a cakewalk.

In any case, I'm not trying to spread FUD here. I'd honestly like to  
get some estimates of language size and implementability. I'm going to  
put my money where my mouth is and do the counts I suggested.
