There's something else you could try - since you can't hide the code, obfuscate it. Hide the real thing in a large pile of useless, complicated, awfully formatted code that would stop anyone except the most desperate (including yourself, after a couple of weeks/months) from trying to understand it. The best solution would be to compile the code, but R is not there yet.
