The terms of the SGA are exactly what they say. I cannot add or subtract a word of it. All I can do is point you to it.
Generally, an SGA gives sufficient rights for project members to work on the code and prepare it for release. If you want to help with that then we'd welcome your help. Send a note to email@example.com and introduce yourself. However, if your needs require code only after it has been reviewed, tested, and voted on as an Apache release, then I'll be equally happy to hear from you then.
