LinuxDevices.com technical editor Jerry Epplin takes a look at SnapGear's uClinux-based VPN appliances from the perspective of a developer's ability to customize them.

Perhaps the most obvious network-oriented devices for which uClinux is appropriate are firewall/routers, which need all the latest protocols and capabilities, but are in a highly competitive environment in which cost is paramount."
