hehe. Here's a salient point:

native block drivers are typically used in one of two ways: creating a
whole subsystem (ide, scsi), or servicing a single host (dac960).

I am doing the first: creating a whole subsystem. The infrastructure
involved in that, over and above what block already provides, is that
part I dread coding.

If I am to code that, I want to do so ONCE. And that means a
bus-agnostic /dev/{disk,cdrom,tape}. Not /dev/{ad,acd,at,ag}.
