Campus wifi? A central server running Moodle as the VLE in each school? It could work very well for them. The further education college in which I work has Windows, but they have installed GIMP, Inkscape, Audacity college wide. Some great work with Audacity, people find GIMP a bit harder. Inkscape isn't used much (but then neither is Adobe Illustrator).
Most of the larger schools (Middle/High) already have campus wide wifi. Some of the larger elementary schools do as well.
The big push right now is for VM Ware. Some of the counties are going to a district-wide WAN for serving up VMs from a central NOC.
That sounds great. Wifi/Internet enabled netbooks in a class one to a group can encourage discussion and carefully planned research if the teacher just thinks through the pedagogy a bit.
