Ad-Hoc supports as many nodes (within reason) as you care
to deploy. However, there is no implicit packet relaying
(bridging) done, as you would expect with an access point and
client nodes. Two nodes can only communicate if there is
a direct radio path between the two.

Access points typically use exactly the same radio hardware
as the NICs. They do run different software however.

So anyway, you are heading in the right direction.
If you need for example two of your client nodes
to communicate with each other, rather than just
with your router, then you will need to enable bridging or
routing on your machine. Personally I'd use routing.
In that case, the two client nodes need to be on 
different IP subnets.
