I too would offer some financial contribution towards some part of upkeeping the licensing or the domain name, or the forum.
Personally on my level and for my own personal use, if there are no more builds or updates to the current VRD Pro then that will not impact me at all, because my current and latest build of Pro has been doing everything that i need it to do for quite some time, however i know others may want more additional features, or are still having issues with some features that were not resolved prior to Dan Rosen passing away.
Cheers
