I think it would be possible over land using GSM, but think of the costs. Airlines should install massive data-centers. And there is no GSM over the oceanic areas.

As you pointed out, we're talking about multiple audio feeds per airplane. But why can't FDR data be streamed back to the company in real time? We're just talking about raw text data aren't we? Surely the bandwidth cost is negligible for these uploads, especially if it is only sent during abnormal changes in power, g-loads or flight characteristics. Even if you can't send all the data over the web, surely something is better than nothing. As far as CVR data goes, you may be right about the datalink system not being ready.
