[Opensim-users] Banning "bad" viewers was Re: Can this be done?

[Imago]

I don't think anyone is understanding. :D It's not just Cryo. I want only 
Linden Lab viewers to be able to login. I've seen it done on other 
opensim's. I know people can get around that. But the point is... Not 
everyone is a coder. So, while they could compile and make it look like a 
Linden Lab viewer then so be it. I just want to know if there's a mod or 
string that I can put in to opensim to see what channel the viewer is 
sending, and if it's not the right one than to display an error message that 
would tell them to download an official release in order to login.

Maybe I should have chosen my words better. Mentioning Cryo is like 
mentioning copybot, and responses only seem to be based on theft and copy 
protection. I just want to know if there's a string to block a viewer. I 
know people have done it I just can't remember what opensim I saw it done 
on. I also know that if I had Cryo source code I could compile and make it 
look like a Second Life release viewer. But not everyone is a hacker or a 
coder or both. Most people don't know how or can't compile a viewer or are 
too lazy to. So, they go look for one, and that's the basis for my thinking 
most theives are too lazy to try to figure out a way and will move on to the 
next target.


So, the question I'm asking is:
Is there a way for OpenSim to check a viewer string and allow or disallow 
based on that, and if so please let me know where that code is, and if 
not... Then I'll be burning the midnight oil again coding one up.
