I use C-clamps to hold mine to the work table, and about a third of the time have it removed and located elsewhere.
This also lets me move it from one corner to another if needed.
My work table is on wheels to accommodate work space alterations, such as when I changed from the horizontal stabilizer to the moveable surfaces, and again when I transitioned to the wings. The vise, which ought to get frequent traveler miles, moves on and off when desired.
