Actionscript 3 :: Streaming Large Amounts Of Data From Flash?

I'm currently working on a project where I generate a large amount of audio data to be stored on a users machine.

It works fine for small amounts of data but as the memory usage grows the flash application begins to struggle and eventually dies.

I've been thinking about possible ways to overcome this problem and I was thinking instead of storing all the data in memory (sometimes up to 100mb) a possible solution may be to stream the data to a server (44100 float numbers per second) as it is is being generated then once the accumulation of data has ended sending it back to the client.

1) can you see any problem with this idea and if so could you offer a better alternative?
2) could you reccommend a good server technology to achieve this?

Edit 1

To add more detail.

I am generating audio on the client using the sound.extract method. As the audio is being sent to the speaker I also send it to a byte array.

Once the user has hit a stop button I prepend a wav header to the audio data in the bytearray and allow the user to download a wav of the audio they have just being listening to.

Ideally I didnt want to impose a limit of how much data the user could save. This may not be possible.Storing all this audio data in memory was causing severe performance problems in flash. I don't know of any way to incrementally store this data on the client machines so I was thinking a solution may be to incrementally stream the data to a server somewhere to reduce the memory load.
