Street Fighter IV: Seth's Infinite Wall Jump setup (READ DESCRIPTION)
I did as search on Youtube before making this and I think this is the first video of Seth's Infinite Wall Jump being uploaded.
Pro players (possibly the ones from Shoryuken.com) might know this.
As the desciption says on the video, it is not really useful in competitive/tournament play mainly because the players wouldn't just stand still. It could piss off a few turtlers (like Guile but can counter it by performing a Flash Kick) since Seth's Foot stomp is an overhead move.
The other problem for this setup is that small/skinny characters (like Chun-li and Cammy) can avoid Seth's foot stomp much easier than huge characters (like Zangief, E.Honda and possibly Sagat) mainly because the different size of hitboxes for each character.
This is a similar example to a trick in Smash Bros Melee called "The Luigi Ladder". 2 Luigis spamming the UP+B move to reach to the top of the screen (pointless in competitve play and requires certain characters).
