No, I can't do this without help from a skilled hacker and yes, there is a method to my madness.
UPDATE: I underestimated my own persistence and the work that the realXtend developers have put into making it easy to install the server. See comments on the first link above. Give it a try - it's not too hard.
MORE UPDATE: This is actually an exercise in getting Sketchup into RealXtend. For Opensim, I found the Windows install very simple, the Mac install of latest builds next to unknown. In any case I will start leaving relevant links here:Posted by Dave at March 21, 2009 12:47 PM
