Funnily enough I have some QEs in DIP as well but I wasn't aware that they have 12-bit ADCs, so it's great then that they do. There is no reason why QEs couldn't be used just as easily of course it's just that the SHs can be run at +5V which could prove useful but either way as long as they can be flashed in-circuit in the same fashion it shouldn't prove to be a problem.
Interestingly if you used a dedicated 8 channel 12-bit ADC converter such as the MCP3208 (non-I2C) then they end up costing you over $4 from Mouser as opposed to the $1.44 for the QE. The MAX1239KEEE I2C chips cost $12.94!!!
I will make sure I test code on the QE as well but I haven't had much time in the past week so hopefully later this week I can start testing the programming interface.
I currently _do_ use the MCP3304 (in 8ch SE mode) so 12 bits is the real clincher for me. In effect I can put secured code in the MC9S08QE "front end", and leave the Prop to do what it does best (juggling other peripherals, in a not very secure way).
Like you I'll be flat out until mid next week, but will order the Pcb's and parts ready to try once the current deluge passes

Any progress on getting intelligible results on the numchuck processor?

The eight gold pins are for GPIO (including 12 bit analog inputs), or jumper based configuration.
I'm waiting on some low profile, self nesting sockets to tidy it up nicely
