Natch.  This is really the next level up; ie. a rewrite of the ATA/
ATAPI support, which is Big Hacker material, but definitely the way to 
go longer term.  This is likely to want to wait on Justin's CAM 
implementation, as otherwise we'll just be duplicating work.

That doesn't sound unreasonable.  It's nice to know that someone at 
Iomega wants to talk to *someone*.
