In answer to jonathanhoey:
One extra thing to certify for high altitude use, electrical wires being drawn, and so forth. Here, on firma terra we don't realise how hostile the environment is outside the airplane. Think Mount Everest and double that. You wouldn't think your gopro worked there, right? Besides that, many pilots feel it's a very palpable breech of their privacy. If you work at an office you wouldn't like your boss to know Every. Little. Detail. about what you do, right?
And for FDR/CVR streaming... I can only say bandwidth, Bandwidth, BANDWIDTH! We need about double the amount of space crap than is already up there for these streaming wishes to come true.
I do hope that all airlines realise the need for ACARS and/or engine monitoring since the MH370 disappeared though.
