Figured this would be relevant to your interests: HSMM-MESH From their website: "HSMM-MESH™ is a high speed, self discovering, self configuring, fault tolerant, wireless computer network that can run for days from a fully charged car battery, or indefinitely with the addition of a modest solar array or other supplemental power source. The focus is on emergency communications. In its current form it is built using the Linksys WRT54GL wireless router and operates on channels 1-6 of the 2.4GHz ISM band, which overlaps with the upper portion of the 13cm amateur radio band. Other platforms and bands may be supported as development resources permit. OLSR is used for auto linking of the mesh node radios. OpenWRT firmware tools are used for firmware development. HSMM-MESH™ is currently being designed, developed and deployed as an amateur radio broadband communications system and being used in and around Austin, and Plano Texas, as well as other sites. Glenn KD5MFW, David AD5OO, BOB WB5AOH and Rick NG5V are the gents spearheading the efforts, while yours truly, Jim K5KTF keeps the website up and running to provide information about the project. There is a distributed development community with significant activity in the Dallas/Plano area and interest growing elsewhere." Edit: fixed URL.
