Why would you want to run AmigaDos under Unix?

Since (a) most anything you do other than actually drawing images involves passing messages, and (b) you don't know the length of a message for copying purposes, this will realisticly mean you'll have to pass messages within a single address space using Amiga scheduling. This means you'll need to run most of AmigaOS in a UNIX process, restricting UNIX context switches to *real* I/O. -- Peter da Silva. `-_-' <peter@sugar.hackercorp.com>.
