There was a free version of Aura 2 DV if you went to a Newtek demo. No dongle on that...there is Mirage which DOES use a USB dongle (same one as LW). If you look hard, you might find a copy for sale. I am a bit partial to mine.
Wait a minute! That bright red, keychain-laden USB widget which shipped with Mirage 1.5b will enable my Lightwave standalone package (for which dongle I lost)? Really??
