[arrl-odv:28716] Third party waiver

Is it possible to get an official state department waiver of third party traffic rules for disaster traffic to/from the Bahamas? Among other things, Winlink is now enforcing third party rules and in order to unblock it they need some sort of official communication that it is legal to unblock the traffic. When I asked Dan Henderson about it, he said that 97.403 should be sufficient but an official waiver is more iron clad. 73 Ria, N2RJ
