You know, seems like there's a huge market here for an actively developed cross-platform nav software that support both raster and vector charts. What the commercial products charge is pretty crazy considering map data (at least for the US) is available free - and the user interfaces are generally bad and cumbersome. A platform like this could be used standalone on a PC/laptop, or on a low-cost (compared to, say, an E120) embedded system.
As a software guy, this would be kind of a cool project. If anyone out there is a venture capitalist and wants to finance this, send me a PM.
