IMO commercial add-ons are a good thing because they offer me choices.
If I did run a commercial trading site I would consider that DLL's
and pay per view, behind walls, would offer as much
protection as can be expected in this day and age although I wouldn't
expect it to be 100% secure.
Commercial extras could add a lot of value to AB.
IMO the real reason there isn't a lot around is because the market is
too small ... only 8000 AB users .... most of us self motivated and
hard to impress ... some of our budget already dedicated to AB and
data .... there is only a handful who have the money and inclination
to buy add-ons.
There aren't many commercial DLL's around because it doesn't pay much.
There aren't a lot of free ones around because we are all too
busy ... community effort takes an incredible amount of time, as I
found out at the UKB.
