This is a great idea. It would also be useful to know which organization they are affiliated with (i.e. ALAC, NomComm, GNSO, etc.) in order to better understand which parts of ICANN are "spending" and which are benefiting from travel support.
I entirely agree that would be useful. The process of negotiating travel costs while I was on the ALAC was a chronic pain, and I got the impression that part of the problem was that there were rules that while unwritten were known to the staff about who qualified for what level of support. It's perfectly reasonable to give some people more support than others, e.g., a board member from Africa is likely to need more support than a random committee member from Europe, but it'd be nice if they were up front about it.
