Region lock shouldnt be a problem, for example if you are on Region A and your BD is b, when playback the BD, the software will change your drive region to match the BD region, automatically.
But only for 5 times, if you keep playback different region of BD your drive will be locked to only one region.

AND, most BD are region-lock free one iirc...

Make sure the BD is playable on stand alone BD player too.
