Hi.

Is there any update on this LiveCD/USB project? 

Not sure how you can imprint wallet address into an .iso, never tried anything like that, but I think if you give people an easy interface where they can enter their address this could be enough.  If UI is too complicated,  you can probably just run a script that will prompt them for an address and then start mining, but not everyone is familiar with terminal console, so UI is your best bet.   You may want to install new clean wallet for people who don't even have one yet (backup could be an issue though as you are mining on live CD, but on USB you could mount it as RW and save all files right there), so they can create new wallet and start mining from scratch.

Thanks.
