Mostly I want this because of piece of mind, but also because I am considering compiling a viewer on Hippo code that will have a different channel code altogether that I will probably use for the sim. If I can lock off viewers that don't have my exact channel or code then I can be sure only official viewers can get in. Right now the sim is only for friends but if I open it up to more I wouldn't want idiots coming in and mucking about the place. Which is why I was asking. I know that some opensim *shaking head* I wish I could remember who and where banned certain viewers from logging in. I'm not sure how she/he did it, though, but it got me curious as to how it's done. That and I wouldn't really want someone using something like Cryo or even Meerkat, but as you said... They probably all have the same default code. But if I put in another code and compiled it off of hippo or Linden's viewer I could put in my own channel and have others not able to enter. I like security and peace of mind, but security in this day and age is a myth. (Like those stupid broadcasting things that were supposed to stop copybot.)
But I was just curious if anyone had done it or heard of it. I want to say openlifegrid did it, but I can't remember so I don't want to say for sure until I find it again.
