For instance, after realizing that Gumstix computers can run ssh, I thought they could make for spiffy remote access appliances: for a bit less than the cost of a cheap clone, one gets a very power- and space-efficient device that can be plugged to a DSL router and power supply and provide secure access to a network (coupled with e.g. NoIP) via tunneling. Another choice I can think of is tinkering with the router's firmware to add remotely accessible ssh to it, which sounds feasible given that almost all major brands are using Linux today. What do you think about these uses? Is it worthy to try and consolidate functionality, and overall shrink the footprint of remote access equipment? What about more complex scenarios involving firewalls, VPNs and the like?"
