The big concerns are how to edit the results if there's a mistake (refs can use their phones to input scores but can input the info incorrectly).
Challonge may not be ideal, but I get the impression it's easy enough to amend as you go. (Adding another round to swiss, amending scores until the round's finished, etc.)
Vince would probably let us know how to run it properly, his email is: tourney@hardcourtpodium.com
