Following the small satellite developers workshop in April there are a number of interesting papers available online.
A cubesat using D-Star which has been selected for launch on the Vega launcher is certainly an eye catching project.

Personally, my favourite so far is the 1U propulsion system capable of propelling a 3U cubesat with a delta V of 400 metres per second. ( This is enough to go from 600km to about 1900km altitude !)
Have fun reading...
