This could be an interesting option to allow very easy use with any machine. Using codemeter dongles might be a good option here as it's a pre-existing method and can allow both USB and direct hardware installation of licenses. They're also much less obtrusive than something like ilok or sentinel, but maintain the security of the license system.
There was a point in the webcast about doing offline installs where you don't have any access to the internet, which this would be a very easy way of solving.
Could potentially go with something similar to what resolume offer, which is the choice between having a dongle license or a software license. This is a one time choice, and licenses aren't able to be switched between the two.
