[Opensim-dev] User services refactoring status

Wed Jan 6 11:44:49 UTC 2010

Thanks for your help here, I will check out these connectors, and  
assess the work involved.

 From my perspective the web interface and authentication are  
critical; the two most significant aspects that impact upon my plans.  
I guess there is a problem in having the development resources to  
update the web interface.  The other major issue mentioned by every  
organisation I have spoken to is security - but I know you intend to  
address this.

I can appreciate Mic's concern though as changes to the architecture  
and interfaces are especially expensive in development time - not a  
demand but it is a significant issue.
Are some aspects of the interface more settled than others? I  
appreciate that this is a judgement call.

Mic do you know who else is doing work on PHP/Web Services?

Thanks once again.
Tom
