Actually, with the recent explosion of Kickstarter success stories (eg Double Fine, FTL), why not consider raising money through Kickstarter for DoomRL 1.0? I understand that commerciality might not really be what the Forge is after, but I reckon it would be a fine way to raise money for a final push (plus drinking the sweet nectar of money is always a fine treat). As it is, the G-version is so pretty that I have trouble believing this is free.
Edit: just realised that copyright issues, etc. Oh well. Maybe a reskinned DoomRL? I'm sure the community is more than eager to help out with renaming stuff. And Derek can get some monetary reward for his spriting, too.
