The PSP firmware 2.6 supports Podcast partially. Here "partically" means it only supports streaming of mp3 files, not downloading to your memory stick.
I first thought this is a bullshit, however now I tend to think this is a nice thing. You don't have to care about the memory stick available size, and you don't have to synchronize PSP and your home PC music library with a crappy Sony's software.
So here's a hack to play iTunes music library on PSP via wi-fi.
- Upgrade your PSP firmware to 2.6
- Install and setup Apache to mount your iTunes library (e.g. My Documents/My Music in win32, /Library/Music/... for Mac OSX)
- Install the recent version of mod_index_rss which supports RSS 2.0 enclosures (Not sure how we can do this on Win32 box)
- Subscribe to mod_index_rss URL (like /path/to/dir/?rss) on your PSP RSS reader
Now it's done! the mod_index_rss module automatically serves RSS 2.0 with enclosures pointing to mp3/m4a files, which can be fetched on-demand from PSP. Now you can listen to your iTunes Music Library @ home from anywhere you're connected to Wi-Fi. Wi-Fi is now available in anywhere, esp. if you're in Tokyo or San Francisco, right?.
Well, the step 2. and 3. might be a bit painful for Windows32 users but if you have ActivePerl, writing a perl server script (using HTTP::Server::Simple) to do the same thing will be trivial.
By the way David and I started the rework of Trickster 2.0 this weekend (inspired by the mp3tunes.com Oboe locker thing) and it'll be a lot of fun.
