All of those are solvable except #3 with a little money and/or shell

1 and 2 can be done with scripts and a handy U5 with USB card (or PC
running linux).  

4 can be done with a better graphics card.  MXE maybe? V8 maybe?  If you
must have 2k, obviously something other than an affordable Octane
upgrade would be needed.  Perhaps an affordable Onyx IR instead? I kid.

5 can be done with NFS as you mention.  Alternatively, you use FC-AL and
a PC running FreeBSD with the SATA drives and a a QLogic 2300 FC card.
Thus you can use the FreeBSD machine as a hardware raid unit (I haven't
tried this, only seen that FreeBSD supports FC-AL target mode, and have
heard of people using FreeBSD as a U160 Hardware RAID).

However, a simpler and more realistic way to fufill wish number 5 is via
Acard AEC-7730s.  Again, I haven't tried these, but their older IDE
cousins work well.  These cards are SATA->SCSI converters.  Attach and
your SATA drive looks to the Octane like a U2W or U160 drive (I'd have
to double check to see which it is).

PCI Sun.  A cheap simple way to get the geegaws working next to the
Octane.  Then, the network is your friend.  Why should you ever have to
realize that they aren't directly connected?

jpilot didn't want to accept /dev/ttyUSB1.  However, I made /dev/pilot a
symlink to /dev/ttyUSB1, and then set jpilot to use /dev/pilot, and
jpilot was happy.  Only potential problem is that sometimes I need
/dev/ttyUSB3 instead of /dev/ttyUSB1.
