I never change my trousers nor shirt, but I have a little compartment surgically carved into my belly where I keep the dongle, …always!..lol…
Nah, I know in advance if I might need the dongle ( with licenses for Elements and demo versions) and keep it in a little hard shell box for safe keeping.
I also carry a Stick with me containing the full version downloads to be able to work anywhere and when if that is necessary.
Also for many Plugins and soundlibraries / Sound-FXs.
These days I test a bootable Win-USB stick with all necessary Programs and data already installed on it. Plug&play, so to speak.
If you have occasionally to deal with unforseeable Jobs or fixes, I agree, carrying the dongle with you at all times is a bit of a pain.
Mind you, my original eLicenser stick is, for many years now, still functioning without any flaws. Call it luck or cautiousness…
But, a temporary license for Nuendo via internet over the MySteinberg account seems a feasible idea I’d fully support.
