Question about launching multiple Guild wars at once

Hello,

I read before that it was possible to launch multiple times guild wars at the same time on the same computer. People told me it was possible if you launch each version on different user session.I searched the forum but couldn't find answer to my questions so here they are :

1)Is it possible to launch multiple GWs on the same session?
2)I suppose it's not (my common sense told me), but is it against EULA or something?

Thanks in advance.

I've found that you can't have GW load up on the same Windows user accounts without modifying the client, which would be a banable offence (according to some). But that goes without saying that if you have multiple user account on your computer, you can load GW on one account, literally switch to another account without logging out, load GW again, then switch back and forth between the Windows user accounts to semi "dualbox". Mind you that you can't log on the same account twice in the same session...atleast I don't think you can =P
