Yes, ConsoleKit/PolicyKit/HAL should be used as the basic infrastructure to properly assign ACL's to devices for specific users. ConsoleKit is the only way to track activitty of sessions, which is what you need for shared devices, to grant access only to active sessions. But I don't think anybody ever really used multi-seat setups, so there is likely stuff that needs to be implemented. > googling around, I've found suggestions for using udev to limit access to > usb devices by creating a group that only has access to the usb subsystem. > > If I want to group some resources and only have those resources on behalf of > a specific user, and not any other, is there a way to do that? You can assign an owner or group to all devices below a specific USB hub. You onlt need to identify the hub reliably. > Can I set up groups for hotplugging usb devices You can assign owners/groups to specific devices, based on matches od properties of the devices, but you can not setup "groups for hotplugging". > and set it up so that the event is only reported to specific group members? There are no user specific events, udev acts at the system level, just like the kernel, it has no idea who receives which event.
