As L0pht occupied a physical space, it had real expenses such as electricity, phone, Internet access, and rent. Early in the L0pht's history these costs were evenly divided among L0pht members. In fact, L0pht originally shared a space with a hat-making business run by the spouses of Brian Oblivion and Count Zero, and the rental cost was divided amongst them both. This was soon subsidized by profits made from selling old hardware at the monthly MIT electronic flea market during the summer.
