Google also think they can run windows executable files.

My idea is about how to use wine in the OS.

Google Chrome has two types of extensions:one is the extension,that support only web technology.the other is PPAPI,Google Native Client.

Here's the overview↓

For example,Flash Player uses PPAPI.

C/C++ programs can be transformed and run in its sandbox.

then we can run wine in Chrome OS.

I think if wine supports Chrome OS,Google helps us.
