I dunno, I would love to see the ability to defer and transfer bibs - even later into the cycle than MCM allows. obviously, the later you push it back the more stress it puts on the shirt orders. In my last few tri's, we allowed transfers up to 6 pm the day before the race. There is a huge delta between 5090 and 22,000 entries, but we were more than happy to make folks happy. It's just too easy to change entries when the entrants do 99% of the work through an electronic form. I do think MCM is missing an opportunity to make a little $ off the transfer. I do agree with their "let me stay out of the trade" thoughts, but think that a fee for facilitating the transfer would be in order.
I think that scalping could be an issue, but then not so much. It's not a high value market like a ball game or concert. Plus, as witnessed by Mouse management over the last couple years, there is a high likelihood of getting burned when the race is slow to close. Plus, it is much harder to scalp a bunch of entries into a marathon. Too much work for too little profit. BTW, aren't tour operators kind of in the scalping business? Don't get me wrong, I have run a tour operator race and loved it, but I always felt like the bundling offered by the operator had to be costing me something, somewhere.
