Chris, I believe nitrogen is no more likely to leak than air (or not significantly so). What comes into play is the utmost importance of installing a very tight sprinkler system, including grooved couplings listed for dry service. The owner generally won't complain if the air compressor runs more than it should, but when he's replacing a N bottle once/week or more often, he can turn grumpy.
