Do I need to have MachTen on each client machine?
MachTen is a complete UNIX operating system, and, as such, includes both client and server components for each Internet service. Therefore, you could use MachTen on every Macintosh. Alternatively, for the client machines, you could simply use MacTCP with your favorite Macintosh client software, such as Eudora, Fetch or NCSA Telnet. MachTen can provide Internet services for any Mac or PC that supports TCP.
