	Yes, it's a totally fuzzy number, and that's the beauty of it.
	If you talk about weather, you can usually say :
		Weather : good - fair - average - crap
		Temperature : 25C - 10C - 0C
	Signal strenght is like temperature, it has a precise physical
definition agreed on by everybody. Link Quality is like weather
quality, everyone has it's own scale.
	So, just decide what you think is most useful, and stick it in
there.
