SolarWinds already propose a demo site for the GA version of the product.
It could be interesting to have also a demo site for the beta version of the product and as such be able to have an idea about the new features that will come to RC and GA version without the need to spend time to setup the beta environment.
Of course we are still happy to participate to beta installation and send feedback but sometimes it could just be easier and time saving to to preview the new feature in an online bate server.
This is of course valid for all the SW products.
Cheers
