ok,about the poll and what I actually believe that is gud nowadays.
I strongly believe that if you(plural) wanna go to private,you(plural)'ll have to find trusted people in order to don't leach/share,which is difficult.On the other hand,public thingy would be better idea for me.Many people are already willin' to help as much as they can.
Just you have to clarify,what exactly you want from this project(people have to let us know too).
A very close to retail svn which will be public?(acis's model to Gracia?) or a fully customized svn?(just custom features,no fixes and such).
If you ask me,I would prefer the 2nd one.
"a fully customized svn".
