Thanks for all the answers (and no flaming, weeee, the LFS crowd is great as usual).
I will test DarWINE on a friends "old" Mac and get back to you, thanks for the great tip!
Regarding VPC, I was curious since the next VPC will be more tightly integrated with the underlying hardware due to the new Intel-based chipset. If it at all started using VPC today, it would be an indication on how it will perform with the next release.
Regarding porting. There still are some open questions, but there really are some worried Mac coders who fear that the ease of porting PC games to MacIntel is going to make Mac-specific coding to be a thing of the past. And since I have a vague memory of reading that LFS does a lot of its own graphic and sound optimization rather than handling it to DirectX-code I was hoping that the platform-specific code would be an overcomingly task, more so than Counter-strike and World of Warcraft (the last one being available for Mac). I have worked in the software industry for over ten years so I do understand that the project would recquire both time and skill. Still, it would be an interesting challenge...
This last discussion would be interesting to put to the LFS team, if for nothing else, to satisfy my curiosity...
More tips or experience is much appreciated! If anyone is even remotely interested, I will post my findings here. There can be nothing wrong with spreading the LFS to an even wider audience...
