OpenACS 4 status -- I'll pass on this one, but you can see the latest
status report
There will be no more new ACS tcl versions. ACS java will of course not be ported to openacs, but aD is looking into getting it running on postgres, as well.
Yes, openacs will run onn mod_aolserver; it's been done.
The GPL only requires you release your modifications if you distribute the new code, so if you just use OpenACS to build a site you don't have to release the code. Of course in the spirit of making life better for everyone you can still release all or parts of your code for integration in OpenACS.
