WINE for Intel Macs?
The Darwine Project has been working to port WINE to run under Mac OS X. WINE is a compatibility layer that has allowed x86 PCs to run Windows Applications under Unix/Linux operating systems. This is accomplished by re-engineering Windows system calls used by individual applications. As a result, the performance of the applications should be native as no emulation is required.
It appears compatibility at this early stage is still limited, but will Mac offer users one alternative to using Windows applications under Mac OS X on the new Intel Macs. A few commercial projects providing the entire Windows environment are reportedly under way, including Microsoft's own VirtualPC application. Also, efforts to dual boot Windows on the new Intel Macs are still underway.
