The first link will be the better option by far. The amount of people it could hold I am not too sure of as it doesn't say the net speed. But it would probably hold a few hundred (depending on the net speed). Just make sure you configure your ascent to "unload" the maps and stuff that are not used, to save memory.
EDIT: Found it says 10mb Upload speed. That should be good for 1000+ probably.
