Since nanites are small machines controlled by small computers, they can be programmed and reprogrammed accordingly. Reprogramming a nanocolony requires a special computer that can broadcast signals on a frequency the nanocolony recognizes; such computers require a Wealth
check (purchase DC 30) to purchase and, depending on the setting, are frequently restricted by the government. Nanocolonies are programmed using the Computer Use skill
Typical commands given to a nanocolony include activation and deactivation, movement (both internal and external), as well as instructions to follow orders only from particular
computers or individuals. Though hacking a nanocolony is possible, changing a nanocolony's purpose can be quite difficult. The hacker must not only overcome the nanocolony's programming, but also must find a way to use the nanite's hardware to serve a new function.
