Distributions/Configurations For Specific Uses?

Page writes "My college (UMPI) is currently reviewing a proposal to collect old hardware from small businesses and assemble machines for those who do not have a PC. The issue came up as to what linux distro to use that will allow us ease of both setup and ability to lock down the machine so once they are out in the field, they cant be tinkered with by accident (thus preventing problems later). These will be used solely for the purpose of web activities (surfing/mail), and word processing and *THATS IT*. Does anyone have suggestions and an idea about how to go about a standardized (or a sort of embedded) configuration across variable hardware?"
