Simply put, I would like to grab a copy of Portal for the PS3, simply for the Steam copy, then have a contest to give away the PS3 copy. My concern with this however is whether or not this will work. I do not own a PS3 and from the Google Searches I've done on the topic, it appears that you have to link your PSN account to your Steam account.

I have a few unanswered questions that I am hoping some of you can help me with.

1. Is it possible to create a PSN account without a PS3?
   
2. If the above is possible, then what would the effect be if I link them together?
   
3. Will I be able to play my copy on Steam on my PC without problem?
   
4. Will the person who got the PS3 copy of the game be able to play it on their account or will the game only work with the account it is linked to?
   

Any idea let me know. Would be cool if this is possible but I am not for sure if it is.

I don't think it will work, but I think you can have a PSN account without owning a PS3. I think you can create a PS3 account just by logging into the PSN network from your computer. Give it a couple days before trying though .. I think Anonymous shut down the PSN website.

Ya... from what I have been seeing, it is not looking like it will be possible.

I may just preorder the game on Steam and give away the copy of the original portal.
