I could be wrong, but I don't think there is a way, at least in terms of PowerPC vs Intel. There are essential differences between these processors such that I don't think it's going to happen. Again, I could be wrong, but I don't think so.
On a similar note, I'd love to be able to stream Netflix on a PowerPC computer, but the web page will simply not do it, and it states lack of an Intel processor as the reason. It would be awesome to be able to set up cheap "Netflix streaming computers" in living rooms, but like I mentioned, I don't think it's possible due to lack of processing power, and probably also code being specifically written for Intel. I've resorted to using Intel Minis for this purpose, and they are great machines, but more expensive than is feasible for some.
