We don't use an OS X server in our small office, but would like the benefits of using ARD. Is this possible or is this an application that will only work with OS X Server connected macs?
No, you don't need OS X Server involved.
just keep in mind that without doing some advanced configuration ARD will only work locely. (not over the internet)
And having two copies allows you to have a remote task server
So you can queue up package installs, choose the remote task server take your MacBook running ARD home.
your packages on the remote task server will still install once the targets come online
