Muni-fiber builds do not by definition serve every address. But to keep this on topic, Comcast doesn't serve every address either! In Ann Arbor, Michigan (home of NANOG), I spent many hours attending the local cable board meetings. Comcast refused to build toward various *downtown* buildings, because the underground facilities would never pay back the cost (never being upwards of 30 years). This is not just an ex-urban issue. When the board explored non-renewal of Comcast's franchise for failing to comply with its contract, they learned that's almost impossible. Court cases around the country side with the industry over municipalities. In an unrelated Michigan case, where a large business signed a written contract (to expand) in exchange for tax abatement (but didn't expand), the Michigan Supreme Court ruled that the contract was mere fluff and hyperbole required to obtain tax breaks and government favors. http://www.michiganliberal.com/diary/7723/ It's a right to make taxpayers pick up the cost of subsidizing private industry

Ironically that device runs a linux-y kernel so is probably also using iptools/tc to achieve the shaping/policing a GUI wrapped around it. The GPL parts of it are at ftp://ftp-eng.cisco.com/pub/opensource/linksys/RVxxxToolchain/ I was also planning to have a look at the hardware in it but that device is now out of my control :( Gord
