This should be how it works already for connecting to an existing ad-hoc
network. But at the moment, creating an adhoc network with the same
settings doesn't happen, mostly because that could pre-empt
infrastructure connections. What we really should be doing internally
in NM is getting the scan list (ideally twice in quick succession to get
a good overview of the environment) and if there are no existing APs for
which we should "connect automatically", check for ad-hoc connections we
can start up.
That might be a problem though, since that could allow users to
inadvertently start up adhoc networks and expose their data in places
like airports or whatever. So in combination with the above, perhaps we
should add a boolean "adhoc-auto-create" item to the 802-11-wireless
setting that users like you could check which would automatically create
the network if it didn't exist. Otherwise, creating a network would
(like now) require choosing the "Create new network" from the menu.
Anyone up for a patch?
