A iso image of a fully functioning WeBWorK 2.4 system is available for download and transfer to a USB flash memory drive.
After installing on your USB flash memory drive, you will have a full fledged Ubuntu 9.04 system with WeBWorK, Apache2, MySQL, etc. installed and configured. If your network uses DHCP, networking will be automatically configured for your system. If your network uses static IP addresses, you will have to configure networking. The system is persistent (if you choose to set up a persistent system), i.e. any changes you make (to Ubuntu, WeBWorK, anything) are saved and will be there the next time you boot the system. Also nothing on your computer's hard drive will be touched so there will be no change to your standard operating system.
For instructions on how to obtain and set up the disk image see http://webwork.maa.org/wiki/Installing_WeBWorK_on_Live_USB
