[Opensim-users] Call to discussion: code environment [Was: recent secondlife client versions don't support OSSL functions]

[Diva Canto]

It may be annoying for experimentation, but it is possible that Linden 
Lab (r)/(tm) is doing this to start addressing the security issues of 
interoperability. Once we have (a) clients running in untrusted servers; 
and (b) servers running code sent by untrusted clients, all sorts of bad 
stuff can happen. Or it may be that they're just doing it to prevent LL 
viewer users from experiencing non-LL servers. Who knows.

But the security issues are valid, whether that's LL's motivation or 
not. It all boils down to trust. One of these days opensim will have to 
start walking that slippery alley, and come up with a trust API for 
servers and clients. I think we have an opportunity to do this right. 
Trust is a people thing. Unlike the web, where people don't exist (only 
ghostly agents defined by IPs and, maybe, cookies), we have people here. 
So the policies can be specified at users' level. LL's static API 
checking seems a bit odd. It may make more sense to ask the user whether 
she trusts the region server.

As for Stefan's idea of an aux client editor for code: have you tried 
Visual C#? It's great! hehe ;-)
Seriously, my group here has been experimenting with all sorts of 
completely different clients to get/post all sorts of different things 
from/into the world. Once the Http server was made accessible to region 
modules, there's no limit to what can be done, really... But for this to 
scale beyond experimentation, we need to figure out trust.
