Virgil Aponte demonstrates [streaming *] a move that slots neatly into the one-armed push-up progression : band-supported one-armed push-ups. After trying these out this afternoon (using a slightly different method to hang the band), I can safely say it'll take a bit of experimentation to find the perfect band/height combination. The Iron Woody green band (as pictured) feels about right for me at the moment.
Something to keep in mind is that the band only remains in place (around the shoulder) with the hand held behind the back - I initially tried a few standard push-ups with the majority of weight being supported by the non-band arm (just to estimate which band to use), and the band kept slipping. Doing them with the hand behind the back was fine.
