This is pretty cool, and from skimming the forum, the Team behind this project seems to be experienced and putting their hearts into it!
If you can get the word out there, and show enough proof of concept to fend off any skepticism, there might be interest in a support/donation channel. Nothing to lose, and it can be great for morale/motivation.
Either way, I'm always eager for a reason to jump back into the classic Fallout universe, so wish you guys the best. If at some point you'd like a playtester for general feedback or game balance, I'm sure I can spare some time.
