It would be shocking if it didn't work out of the box; the RPi is just another $45 Linux box--although with Newark wildly guessing "141 days lead time" on stock, you may find the slightly cheaper Pogoplug more interesting if less featureful.

If you mean "run Lua on bare metal RPi", you'll be limited to the released peripheral documentation, and whatever can be deduced about the hardware from the Linux source code, bootloader, and binary blobs. Broadcom does not require you to order 10k chips to get hardware documentation, but by reports they at least want to see a plausible business plan before reaching the NDA stage. 

This isn't that unusual; I don't have a datasheet on the (say) RTL8196C either. At least the RPi is explicitly marketed to be tinkered with, unlike hobbyists reverse-engineering other hardware. Platform stability is nice too; consumer hardware often gets radical architecture changes between different hardware revs.

My hardware-of-the-month is a Atheros AR71xx 802.11n router; it's $17-21 refurb or $32 new. That includes tax but not the cost of traveling to the store and back. It's fully supported in OpenWrt stable, which of course uses Lua to implement the web configuration interface.
