Route audio to handset earpiece?
 

Is it possible to route audio output from the Media Player and web browser to the built-in earpiece on the N900? I.e. the earpiece that you use when you hold the phone up to your head?

Sometimes I listen to voicemails which come as email attachments (and so play in Media Player) or which I can access on the web in a flash player, or I might want to listen to voice memos that I've recorded on the device. I want to be able to listen to them in private, rather than everyone else able to hear, and it seems a shame to have to plug in headphones when there is already the earpiece built into the phone.

Shameless bump - surely this is technically possible?
