I don't know the specific answer to your question, but I do have an alternate idea:
You could always partition a hard drive and dual boot OS X 10.6 and 10.7. Not quite as nice of a solution as virtualization, but certainly better than purchasing another machine (or not upgrading an existing machine).
The license for the base version of SL doesn't allow virtualization (the Server version does.)
The transition of the Mac platform to Intel processors was announced six years ago. The last PowerPC Macs were discontinued five years ago. Whatever PowerPC application you're running is dead. In the long run, you're going to have to migrate. You might as well get it over with.
The whole license thing appears to be in flux right now. Is your info 100% up to date, or are you just pulling up old files?
Your second comment is useless. Reread my very first sentence. This isn't a choice. Some of us out in the real world HAVE to deal with legacy issues that arise around IRREPLACEABLE hardware and software. So we figure out the best work-arounds we can.

Excellent point! And good of you to introduce it into a thread that others will refer to.
I make all my external drives bootable, and I intentionally leave the older versions of Mac OS on some of them. On (rare, thank the gods) occasions, this has really saved my bacon.
Unfortunately, for daily workflow, it's even clunkier than my mentioned alternatives, since it means entirely shutting down a machine and interrupting any workflow in progress to acces the Rosetta function. Doable, but not fun.
'Course, I've no guarantee that virtualizing SL will actually work-- virtual environments can get hinky about correctly seeing external I/O. Dunno until I try.

So, what's the word, yea or nay?
Nay. The release of OSX 10.7 does not change anything with the EULA for earlier versions of OSX. Apple will have to announce a specific change to the EULA for older versions of OSX.
That said, it is already legal to virtualize OSX Server 10.5 or 10.6, with the restrictions that the virtual machine be run on Apple hardware, and you have purchased a separate license for each virtual machine. Leopard Server and Snow Leopard Server do include Rosetta so at this very moment, it is very possible to run Rosetta in a virtual machine legally. It is not financially practical for most people since OSX Server is $500 retail. But if the question was strictly about legality of running Rosetta in a virtual machine, then the answer is "yea".
(BTW, before you ask if this is my opinion, I was very active on the VMware forums for this subject. The above statement is the official interpretation from VMware. VMware, being the leader in the virtualization industry, I have complete respect for the correctness of the statement, despite my not fully agreeing with some of the interpretation details.)
Thanks for settling that. I've posted a request for this to Apple Support.
Hopefully they'll decide to loosen things up for old client OS's. I can't see an economic downside for them and it'd take some pressure off them when legacy problems arise.
The VMWare fora are great. I used the frequent them before I switched to Parallels (yeah, I know, turncoat). Buncha really shmaht guys.
