Re: Old news.
If you want to go above 100km altitude you will have to switch from "flat earth" to "round earth" trajectory calculations, i.e. polar, cylindrical, or spherical coordinates. The usual x,y,z may be more difficult to use (but not all that hard actually). You will also need some decent tracking & telemetry, perhaps via DoD access? That would suck. Then again how much would multiple, worldwide, radar tracking stations cost ? You would also need clearance from many different countries, and an agreement to return your equipment should it land on within their borders.
If you could actually get a payload to orbit, maybe you could pioneer electrodynamic tethers to gradually raise its orbit to geosynchronous. That'd be something eh?
