[sudoroom] electronic access

[Andrew]

David: The electric strike wont work because of the kind of door it is.
Replacing the bar is really the best solution so far.

Steve: buying a ton of keys is just not sustainable, and doesn't give us a
way to easily revoke access if we need to.

Marc: I'm of the opinion that we should just present this solution to the
group at the meeting on Wednesday. I know that there are people willing to
front the costs and work to get them recouped later (whether it's through a
deal with other tenants or a budget decision through sudo room).

You will also have to add to that the cost of automatic locks for the
internal doors. If we keep the elevator up we need two.. down we only need
one.
