From experience, the stab isn't the best place to mount a laser, and definitely not at the end of the stab if the intent is to actually aim with the reference; because the stab generally sits much lower than the arrow, you have to angle it up while the arrow drops down into the POI, gives you a very specific distance at which they will intersect; move back just a bit and your laser points significantly higher than the arrow will impact. Whole set up will be less sensitive to distance changes if it's mounted up near the bow's sight mounts, but then it's still like using a fixed single pin, you have to figure out the over/under at different distances.
Another problem many bow laser users come across is the target panic that comes on trying to aim with the laser- your pin float appears to be significantly smaller with a regular set up, and is wickedly wide/off target with the laser.
Will it aim the same for different shooters... Maybe closer than a reguar pin and peep rig, but won't be dead on as archer form/execution is still different.
Typically, their greatest use is found in not using the laser to aim, but rather pointing somewhere outside your field of vision; then video your shot and the laser movement and use that to work on steadying your hold on target.
And no, have never come across a "programmable" laser for multiple distances; My set up has windage and elevation adjustments that someone could, with a lot of time on their hands, figure out how much to change for different distances, but the whole thing would be thrown off by up/downhill shots anyway.
They are fun to play with; I'm going to set one up sometime so a spotter can help me shoot some 3D, but expecting only the lowest probibility of success on even hitting the target.
