Yes, I'm currently going to give a little private training to korchi about Pokemon.
But ddude, with the pre-order disk in question (in fact, the very disk korchi speaks of is the same one I speak of), you can, in general terms, get an infinite number of Jirachi from it. There is no limit to how many Jirachis you can transfer from the disk to a Ruby or Sapphire version. From there, someone can transfer bunchs of them a day (especially if they have both Ruby and Sapphire, or even multiple games of the two versions) to GenIV games, and then spread those out over Wi-Fi. Yes, if you lack the right connections, it would seem hard to get. But if you take one glance at SerebiiForums, which I do very regularly, you will soon realize that its status as an event legendary is almost an illusion. Even in America, Jirachi is nowhere near as elusive as the likes of Deoxys, much less Celebi.
By the way, Coronis at SerebiiForums (Coronis is practically Joe's best friend/right hand man there) did a lot of in-depth analysis of the coding in the game. Coronis to Pokemon is kind of like Zonexus to MLN. Anyway, Coronis has done in-depth looking into the games (part of this in-depth look is what discovered the whole Soul Dew thing, as well as a few rare tidbits), and Coronis has clearly stated that there are no in-game events for Mew, Celebi, or Deoxys, as some have speculated. Not that the events would really be necessary anyway. Mew can be gotten off of MPR at anytime, given you have a Wii with Wi-Fi. Deoxys had his event last year (I always thought the voting for that event back in 2007 was staged, and now I think that even moreso). Celebi is going to have an upcoming event very soon.
Hey, guys? We should start spreading around BT's banner. Also, could you guys put it in your sigs at MLNTeam? I think there's an untapped group there that could compete and join us here, and they haven't done so yet. This might persuade their interest. It could aid in building up numbers for the tournament.
Yeah Jirachi is kinda like catching a Pidgey to me. All I got to do is hook up my old GameCube and Infinite Jirachis.
