right now, we are only in the planning phase of restarting the project, so it's difficult to say what will be done, and how.
as for your questions:
- the game is an unofficial sequel to the street rod series.
attempts were made to find the copyright and license owners, but we were unsuccesful.
so it's most likely, that the game will remain an unofficial version.
- the game started as a GNU project, and went open source in 2004 i think.
since we are yet discussing the technologies to be used, we can't say anything for sure.
open source is likely, but that remains to be seen.
- you will be able to download the game from streetrod3.com, but i'm quite sure it will be mirrored on other sites as well. however, it's advised to use the "official" download sources, which will be listed on streetrod3.com at a later time. these locations will always contain the latest version of the game.
if you have further questions, please ask!
all the best!
