Summertop: These tournaments typically run a week. A week long tournament? How's that supposed to work? Not many people will be able to go without sleep for a week.

Note that in my suggestion, once you start the tournament, you got to stay till you're eliminated - there are no time outs or breaks. Now, a time limit may be a good idea - let the tournament run for one or two hours, and count the chips at the end. (To avoid people waiting till the last second before raising/betting/calling/checking/folding once they are ahead close before the time runs out, hide the exact time when the tournament finishes, or let a tournament be "1 hour + 20 hands", meaning that the tournaments ends 20 hands counting from an hour after the tournament started).
