Well, I was thinking to youtube videos streaming... Since it will be 
impossible to see them in embedded browser (without local javascript 
hacks), I guess that we could use an application (if I'm not wrong 
someone is developing it on projects.openmoko.org) that fetches and 
plays (on streaming too) the videos in other formats supported by 
youtube (you can test them using youtube-dl -f <value> <url> [1])

The formats (fmt) that should work with no problems are:
  * 13: 176x144 at 15fps 3gpp file so H.263 video and AMR Narrowband audio
  * 15: 176x144 at 12fps mp4 file with MPEG4 video and AAC audio

Another format that maybe works on streaming (if I've not misunderstood 
what has been stated) is
  * 5: 320x240 at 30.000fps flv file

Maybe too low, but... I think that actually it's the best way quality we 
can get without rencoding it locally or simply without using a 3rd party 
server doing this work for us "on the fly".
