I strongly suspect that, in 10 years, the "laser module" will have 
changed some minor-to-them but major-to-you component.

I'd go with the laser pen idea, and buy 25 of them.  Strap them to the 
inside of the top of the case like spare fuses, and let people just snap 
them in, like spare fuses.  The ones I hacked up no longer have most of 
the body preent, but that leaves a very nicely sealed can for the 
average non-geek to pull out and snap in as needed.
