), the latter of which would not have been a valid domain name at the time of its founding. The original idea for the name was simply "Lopht", but another member of the Boston hacker scene, Majikthys, suggested a 0 replace the o, and the idea was swiftly adopted.

History

Products

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 between 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 between these. This was soon subsidized by profits made from selling old hardware at the monthly MIT electronic flea market during the summer.

Occasionally, shell accounts were offered for low cost on the L0pht.com server to select individuals; while these individuals had access to the L0pht.com server they were not members of L0pht. One of the first physical products sold for profit by L0pht was a POCSAG
