Hmm, is the "general consumption" of the network support a matter of weeks, or months rather? And what about the block device? As I understand, using SCSI emulation gives better results, but still, there will be a noticeable difference when compared to the "native speed". >> Are Windows PV drivers planned, too?

Is it decided if these PV drivers will be open source/free, or rather have commercial model? -- Tomasz Chmielewski http://wpkg.org ------------------------------------------------------------------------- Take Surveys.
