I have pretty docile bees, but I don't like hanging around within 6ft of the hives when I can avoid it. If you have an empty apiary then low growing plants might be ok to get established, but anything that needs regular weeding to keep the grass from invading is going to lose out.
That is the beauty of subterranean clover. It is low growing and smothers out the competition. He'd probably have to rough up the ground a bit first and over seed heavily but it should out compete any other plant. I have a subterranean clover lawn in the works myself. I broadcast sewed the seed, it's coming up, all is good.
I also know creeping thyme is a quick grower that can out compete other plants. With creeping thyme it's best to start it indoors. When it begins growing out of it's container you plant it in plugs where you want it to spread.

Good pics of creeping thyme establishment here.
So perhaps wood chip, plant some creeping thyme plugs. Problem solved.
