sounds good to me. the end result should be nothing short of a usb stick that you can cram into the tablet's port, that does the wipe, install, configure.
given the nature of embedded devices and the lack of space, we'll have to make versions for the tablets we wish to support...
for example, the system compliment of my WebDT 366 is:
* AMD (NSC) Geode GX2/533mhz
* AMD CS5536 supporting chipset
* AMD Geode display chip
* Penmount DMC9000 4-wire resistive display attached to /dev/ttyS0 at 19200bps
* Cisco Aironet 350 PCMCIA 802.11b card
all in all, a fairly well supported unit. I was surprised. I did have to get Penmount's driver (which did have source code, but you can't use the driver in xorg).
as an aside, Do you have ANY idea how challenging it is to shoehorn a "well, it needs to be embedded and then some" setup into 512 megs of flash? whee.. it took me 6 tries to get a system build small enough to fit. The irony? it was less painful than trying to get a working WinCE orbiter.
