Onoway, geofspa and I have considerable experience of running BBO team tournaments over the years, but one of the big differences is that we have had a 'committed' set of players (IAC, BIL, Acol Club, my local club). So not only are people generally present, but there is prepared set of interested kibitzers ready to fill the red void. I guess Jacki's experience with the ACBL tournaments is similar, in that people are financially committed and so more likely to show.
I think one lesson from this event is that running larger team events, and longer ones, will require a model where it is expected that (i) people do not show and (ii) people will run at some point, whether for good reason or bad. Perhaps starting matches with empty seats that the players, or director, then fill is a viable approach.
It is interesting to consider what tournaments are likely to be popular. 8-10 board tournaments currently dominate to landscape. Team matches are typically of the same length. Of course this is too short for a teams event. Speaking to my team mates and friends, it seems like 20-24 boards would be feasible. An eight team round-robin, playing 7x3 boards for example, seems ideal to them. Even 7x2 boards makes it an interesting experience. A small round-robin is more attractive than a short swiss event, since you have a fair chance of winning.
However a round-robin would probably need to run as a BBO tournament runs, with the movement automated within BBO and not by external systems, given the number of matches required, although all the matches/line-ups would be fixed at the start of the event.
Actually I quite like the idea of a eight team round robin
