Devices already exist. These have been used by yachts for several years now.

Interested to see how are they going to record and store high-quality audio of 25 h
iPod nano? :-) One would need about 1.5 GB of memory using bog standard MP3 @128kpbs, which should be trivial in this day and age. Before anyone asks, it's around 15GB using uncompressed PCM @44.1kHz/16bit (Audio CD quality). My mobile phone has more memory.

A possibly loony suggestion: how about a last-ditch submerged signaller consisting of a large block of metallic sodium sealed in a crush-proof container and venting through a tuned pipe. After a month or so submerged, the seal across the vent dissolves, water makes contact with the sodium, and instant LOUD steam whistle results.

A series of ground/sea(moored) base collector stations could down load data automatically from overflying aircraft in remote or any area. This would be in the end, far cheaper than satellite based operations.

A very large amount of data could be sored for say 1-3 months, then rewritten over.


Global Coverage

Today, HFDL is an air/ground data link standard with coverage in virtually every corner of the globe, approximately 168,000,000 square miles (440,000,000 km2) where aircraft are never out of touch both in the air and on the ground.
Evolving Technology

The HFDL network and avionics are a continuing evolution. Recent innovations in avionics software developed by both Honeywell and Collins have enhanced performance and contribute to the service’s outstanding message success rates. There is continued investment in the HFDL infrastructure and there is a long term strategy in place to ensure its success.
ARINC have been quoted as saying that the system and its use have grown at rates above 20% for each of the past ten years and it now supports over sixty airlines with well over 1,200 aircraft sending more than 1 million messages a month. In 2009 eight new operating frequencies were added which brings the total number of frequencies to 167 worldwide.

Simple low-cost solutions could be easily created, but probably take time to get authorised and integrated.
There are millions of devices out there that can store many GB's of data and are freely available. Most are of such capacity and capability to be very small and strong enough to withstand most crash scenarios.
Encase any (two) such devices in modern airliners and located them in opposites end of the frame.
Continuous recording loops can be used for days not hours of operation and minimal wiring will be required to do so, thus reducing the weight penalty. Some of these devices already have their own GPS so don't need to rely on heavy aircraft systems integration.
Transmissions of these devices can be made autonomous depending on capability of other hardware installed, using phone signal to SatCom as required, VHF or HF as installed...
