Is there any reseller software?

Okay, so like I'm a server chillin` like a villan outta nowhere I think some reseller software would be awesome, and I know there is some open source stuff for this out there, I just can't find it. I guess using a webstore and CMS or whatnot might work but that's ugly. Another application it looks like Steven's going to be "writing" this summer which really means planning and not finishing. What a lame waste of time, plan out cool applications then not writing it, sometimes I wonder can he ever finish a project that's 1/3rd as complex as a nice block of code.
