My only concern is Apple's patent for this: http://www.google.com/patents/US20100153929

Well good news is that it is not a granted patent yet. Although it looks like Apple is fighting it to the teeth and most likely discussing reduction of claims (check the PAIR system).

Regardless if its a patent or not, what is being described here doesn't seem to be infringing on the patent anyway.

See the first Claim #1:

PART1 <storing a device-independent intermediate representation of a source code; > and PART2 < in the event an indication is received that the source code has changed, using the changed source code to generate and store a new intermediate representation of the changed source code.>

If I understood correctly, only thing you would be doing is the PART1 hence you are NOT infridging on the patent.

IMHO Disclaimer= not a lawyer, dont follow any advice you see here ;-P

Julia, Rust etc. languages are already doing it.

The patent specifically targets compiling JavaScript to LLVM and running a monitoring daemon to update the IR when the source changes.

It is ridiculous.

It is a general compilation process, applying it to these specific conditions is in no way technically original. I hope it isn't from a legal standpoint, but IANAL...

I'm aware of that patent long before and not following the same structure. Besides, it also targets other languages by saying 'Javascript or similar'. No worries here. Thanks for reminding.

and Lua .. how Unity3D uses javascript is also related.
