Many may have seen the post below yesterday (or the one from Tateru Nino)
It really worked. Today i was able to get an OpenSim up and running from my USB drive on my laptop. See pictures below. Some have asked why? Free full sim (full prim) developement sandbox is one thing. Anything created there could be uploaded to SL (of course at a cost of $10L per assest, but no more paying for trial assests).
I will be interested to explore this further. Is it possible to have friends access your usbSim remotely? Possibly not. But there is much more to learn about this. Folks have had clients (viewers) on usb sticks for long time, but this is the server side as well. It sets you up with MySQL and Apache server... I then loaded Imprudence onto the stick... and both ran flawlessly (well... after some tweaking) on the 6 yr old laptop running with Vista.
I probably didn't need to black those out... I freely admit my ignorance there... but all you need to know to set it up, can be found by following the links from New World Notes and Dwell On It listed above.And for more info (certainly over my head at this point) try this link you can also read from Pathfinder himself at
Be Cunning and Full of Tricks.
If nothing else... I learned a lot and look forward to exploring the potential of my Sim on a Stick
