I'm also wondering about the feasibility of taking these gizmos on airplanes, what with the Lithium battery packs, etc.
What we really need (for some definition of need) is a robot-filter-remover, timed to deal with the two critical times (first and last instant of totality; 2nd and 3rd contacts from memory). Anybody out there interested in building something like that? It would be purely a passion project, because it could only be used a few times a decade...
