Concerning transportation: We usually meet in Europe. Europeans can by cheap flights for even 100 € two ways. But when Richard and Bo want to join use, they cannot buy such cheap flights, so when we have 300 € for transportation I think it is fair to give them the money. (Just a thought.)
I am not sure whether this has been done in practice, but I remember of cases were we proposed to sponsor people who could not come (just in case the reason is money). So the general rule is "no transportation" but rules can be
adapted depending on what money is available.
