several questions ps3/psp

Can i use a psp to receive streaming content over the internet from my
ps3 when the content is not on my ps3's hd, but rather on a nas server
streaming content to my ps3 (using twonkymedia) ?

Another question: when i stream content over the internet from my
ps3 to my psp, can i then somehow copy the files from the psp to a
remote pc for example?

Last question: when i use the psp to control my Playstation Eye, can
i record/save the video/images to the psp?

thanks
