Not sure if I'd recommend using the nanoFlash with 2700/3700. The AVC Intra format is 10bit and the Nanoflash is 8bit. Unless using Compact Flash cards is more convenient than P2 Cards, I'd stick to P2 for master quality.
OTH, on a tape-based Panasonic camera, the nanoFlash would be a great way to get a file-based workflow thats cheaper than the P2 Mobile albeit with a qualitative difference.
We like the nanoFlash for Sony EX1/ EX3 for the 4:2:2 bit depth and better quality, for turning tape-based cameras into file-based ones, or for dailies on more robust systems. They have great versatility.
