Brooms and Wandless Magic

My apologies if this has been hashed over in the past. (I tried to look 
it up under "brooms". Bwa-ha-ha-ha-ha, the word appears in a majority 
of posts as far as I could tell!)

Are the brooms WW folk use specially charmed/enchanted so they would 
fly? If so, could Muggles use them? (Perhaps they are excepted from the 
usual ban on enchanting Muggle artifacts for reasons of tradition?) If 
not, does this mean that in theory any old broom can be used by a 
witch/wizard to fly? Since we don't see people waving their wands to 
activate a broom, is this another example of wandless magic? (Along 
with Potions, LV's legilimency, and other examples?)

What do people think?
