Well, I guess LL will register and do whatever it takes for if they don't, one way or another, I think they wont have much of an economy left when the dust settles. Regardless how the big Merchants and land Baron make out all the small interests add up and, lets face it, a big attraction to Second Life is that people can make some money if only to off-set the inflated pricing of simulators. Money is made from more than content sales since the large Adult section works on things like tips, donations and escort fees, etc, etc. Fine if LL allow people to use what they make towards paying their tier charges in a closed economy but I still think that, over all, the economy would shrink and there would be more drift to Opensim grids and other virtual worlds where they can still get profits out of the system.
No bad thing for the free Metaverse of course!
