Hi a,
Just remember, there is no reason to believe you can't have a Snow Leopard partition separate from your Lion partition, or a second hard drive for Snow Leopard to continue to have Rosetta access.
Unfortunately if Rosetta is demolished with Lion, new machines that come out after Lion's release would likely not have the ability to run Snow Leopard or Rosetta
Yes, that was what I was referring to. Though I despise booting back and forth between operating systems to get things done, a person could always do that as long as they have a Mac capable of running Snow Leopard.
The main problem of course, and what users are really concerned about, is newer Macs which will only run Lion or newer. Someday, I will need to replace my Mac Pro, then what? I've heard of a few possibilities.
1) Apple didn't write Rosetta. It was based on Transitive Corporation's, QuickTransit. IBM bought them out and now have the software, which they released as PowerVM.

So it's possible that IBM will see a sales opportunity and make PowerVM available to Lion users who need to run PPC software.
2) Apple themselves could make Rosetta a separate purchase for Lion. That all depends though on the licensing rights they have with IBM. That it's possibly run out may be why Rosetta isn't in Lion in the first place. Who knows though, it could still be put back in before Lion's official release.
3) Lion has the Server upgrade available as a $49 purchase. From what I've read, the rules for what you can run in a VM will include the non server versions of Leopard or Snow Leopard, as long as the VM is on the same Mac running Lion Server.
But there's a problem there, too. At least for me. The scanning software only recognizes the scanner on a FireWire 400 port. Right now, all VM software only support links to USB ports. Since Thunderbolt is a derivative of FireWire, there are already FW400 and FW800 to Thunderbolt adapters available. Users of these scanners have already confirmed that the software can find the scanner on a FW800 port using a FW400 to FW800 adapter. So a FW400 to Thunderbolt adapter should also work. But the VM software itself would still have to be updated to include a link through to Thunderbolt ports.
