Would people be interested in using this kind of program?

I was thinking of developing a program for the purpose of hosting ladders and tournaments.  Before I develop it, is there anyone interested in using such a tool?

This is what I plan to have the program do.  All of this will be in Java for the purpose of platform neutrality.
-Choose either tournament mode or ladder mode
-Allow the user to create as many new variables as they would like
-Allow variables(such as points) to be fixed by formula decided by the user


There are few other ideas I plan on using but I also want input from potential users.

Any ideas you would like to see in this program?

Dude that would be an awesome program. If you create it I will use it for sure. Please create it!
