- A SCSI target - iSCSI initiator dongle
A what now?
- A wifi card for the Duo modem slot. Or similar Duo wifi solution.
That's doable, if you have monies. Serial to wifi modules are around, some that appear as Hayes AT modems at the serial end. Not exactly cheap though. There have been threads here discussing wireless Duos (insert usual search prompting here), and Sparkfun have the modules/ICs.
- A nubus or LC PDS development card
Hey now... Not a bad idea at all. Esp with an FPGA onboard.
- A diskless booting solution
Also not a bad thought. Do you have any informative links on the two you mentioned?
