We are currently planning a party for a friend and I wanted to load some videos on a server then hook it up with these powerful outdoor AP (its a big hotel) then have all the guests log in and stream the video(via XMBC or MediaTomb) to their devices (720p and higher video mark you)

I have several questions
  1. Do these Access Points have a maximum no of users who can be connected?
  2. Do they have a maximum bandwith?
  3. What are the disadvantages of these idea and what should I watch out for?

I haven't made a decision on which to buy so go ahead and suggest whatever you think has the highest no of simultaneous users and bandwith
