This is so cool. Can you put this on the wiki? We have a nice list of
these companies growing!
Also, question about the DSC. Just conjecture, and I know very little
about DSC, but what would it take to get a small little DSC optics to
fit into something like the Ben? Something like the 8963. Also, how
possible to drive something like this to freedom?
Curious for a few reasons. Apologies for misused terms.
