I know this has nothing to do with what Freak asked about, but I wanted to add this.
Personally I've never run into a site that won't allow multiple accounts from the same IP address (afterall there can be multiple players living at the same place). Usually the restriction is about having multiple clients running. By not allowing multiple clients they can put a damper on collusion. So just logging in to a different account should be fine.
I'm not so sure about this anymore Jack. I know on JetSet months ago you could have two users from the same computer(of course not at the same time) But when I went to sign up my mom on my Dad's to add her on the JetSet account on their computer a week or so ago, I got everything typed in and pressed finish and a box popped up saying you already have an account on this computer.
On a different situation, I had to get special permission from JetSet on our computers, for my hubby and I to play a weekly league on the same IP. Four emails later and we were approved. We can play in the same buyins or MTT
freerolls but not at the same ring games. (I know this is the multiple clients on the same IP)
I do believe that Paradise is going this route also. I think after the fiasco late last year/earlier this year was it at
pokerstars? With that kid playing on his Grandmother's name and winning that major tournament. It also discourages others of signing up on multiple user names for a buyin or freeroll and playing then signing off then signing back on with a different user name.(This is what that Kid did) I think this is sometimes why there are many sitouts for tournaments especially freerolls. Even though I don't have proof of this but it sure makes a bit of sense to me.
I'm not sure how many rooms are going this route with the IPs and the same computer but I had heard that a few are going there if they aren't already. I just don't know for sure since I already have accounts and some multiple accounts for Larry and I at many of the rooms that I have downloaded in the past and have had these for quite a long time.
Now I do know that if I want to play on JetSet or Paradise I can play on my parent's computer with no problems. My first deposit infact at Paradise 2+ years ago was on my parent's computer where I originally signed up the account.(Back then I know they allowed multiple users on the same computer)
I guess I went on a bit more than intended but I just wanted to add this information, it may be helpful to some.
