Sending guitar through AC30 IR will not sound the same as pluging guitar into real amp. IR contains just static (at fixed input level) filter and phase information, no distortion. Real amp/speaker combination is so much more than any IR.
I thinx VOX wouldn't care much if you make IR of their amp - all you really do is send a signal through their amp, and record it. How you process it afterwards (make IR of it) is your own freedom. By making IR out of AC30 you don't replicate AC30 in any way, you just mimic its frequency/phase response with digital filters.
And for cave, probably you will need permission from cave owner to record there. What you do with recording then is your thing. With IR you don't recreate the cave, it is just a simulation from one single point in cave to another, and often it is not close to real thing, especially if your IR's are not "true stereo". Acoustic spaces are much more than one single point to another, you move a little and it all changes, and IR's can't do that.
And don't worry, your recorded IR's will not become next big thing in value, market is full of IR's already - unless you plan to make software that is better than Altiverb or similar, then you may need to solve some licensing issues.
