What do you think of this 'portable' setup?

[Douglas Carmichael]

I'm speccing out an audio rig to use with my PowerBook 17" revA (60GB HD, 1GB RAM) and I'm wondering if you have any comments on my proposed setup. 
  
 Console: Yamaha 01V96 with MY16-AT 16-channel ADAT I/O card  
             (in R&R ATA case) 
  
 Rack: 12U R&R ATA shockmount rack with: 
         * Furman power distribution (1U) 
         * FireWire hard disk/CD-ROM (2U, who are the good makers other than Glyph?) 
         * Mark of the Unicorn 828MkII 8ch audio I/O (1U) 
         * (2U blank panel for expansion to 24 tracks) 
         * (1U blank panel for MIDI TimePiece AV) 
         * (future expansion including outboard FX, etc.) 
  
 Software: Which software would be the most flexible for HD recording with eventual expansion to MIDI? (I want to be able to do basic recording/mixing but also want to expand to surround mixing, locking to SMPTE, etc.) 
  
 Will I be able to mixdown to a 2-track/6-track file on disk or do I need a separate mixdown recorder? 
  
 Would having the disks and the 828s/other interface on the same firewire bus cause a problem? 
  
 Any comments welcome.
