For what it's worth, I volunteer to be "temporary" lead dev for the windows spring, at least until we get to The Merge. Because none of the SY's want to, and Buggi hasn't said anything either, I think I'm the best suited person for it right now. Working on the AI interface has made me find out a lot about how spring works, and I've got a lot of game prog. experience in general too.
What I will be doing will basically involve supporting the new s3o format, making the linux code work on windows, *trying* to fix bugs, applying patches from other people and starting with some AI stuff together with dj_oldfield. I have a decent amount of time to put into spring for at least the next two months. I can't promise too much though (maybe I already did), the first two things are my biggest priority, I think getting that to work will be an incentive for other people (possibly linux people) to do more on spring as well.
JCAI will be on hold for a while, or more like forever because cain and I are planning and discussing a long-term global AI solution based on parts of my AI and his and new code that we're going to write together, and I'm discussing an AI core improvement with dj_oldfield.
These AI ideas take a while and initially need to developed as a seperate branch anyway.
Note that I would do these things even if it wasn't as "lead dev", but people should know that although spring will slow down much with SJ leaving, it will not go on a downward path and still be actively developed.
