I am confident that AOL has already shown that they can work with the community. Everyone is aware that OpenACS is probably the biggest user of AOLserver outside of AOL. So I am confident that whoever is on the core team will support OpenACS.
There are other ways to contribute to AOLserver and stay involved with it without being on the core team.
There are weekely chats and this week one of the main topics was getting the ad13 patches into AOLserver. So as long as members of the OpenACS community remain active in the AOLserver community, that will be enough.
