MPC

The site consists of simple elements, wired together in a complex way. Looks easy at first, until you dive in. A developer friend initially said "oh that's no problem" until he realized the complexity "you got your work cut out for you". It took a month to solve this problem "how will housing administrators configure this product". Solved ! Unfortunately the really hard part lies ahead, in the programming.

Every apartment in-the-world needs this. Income potential is "interesting".
