We have a very simple bob-adapter now for the TangNano9K Board:

Hey, any thoughts on making it configurable via SD card config like the regular remora? I notice the tang has an SD card slot

no, if you change the config (IO-Functions), you have to generate a new bit-file.
it's far away from remora, only the linux-component is adapted from remora.

because there is no softcore running on the FPGA it is difficult to connect such interfaces.

but you can use one of this two modules to add UDP support:

Ok np, next time.
flash & wiring ok - working.
Question:
Driver have pid? - why not standart linuxcnc pid ?

Do you mean inside the linuxcnc-component ?
this is based on the remora component and it works for me ,
so no reason at the moment to change it :)
