[sldev] Voice =/= Proprietary

[Sylvio Deutsch]

I personally am against voice in SL. I think the chat part is one of the 
main character features of SL and wonder how many residents don't want it to 
be much closer to reality than it is now, like me. I've talking around and 
most people don't want a talking feature.
But of course I can just turn it off...

But what bothers me a lot is that there is a ton of lag occurring all 
around, I'm for one month having to deal with trying about 15 times (no
joking, i counted many many times) to take anything from my inventory, and I 
just can't understand why adding something that will be a burden on 
connections wihle these problems are so much more important to solve before.
