Is it possible to make an Go port out of the jtag header?, or are we getting an Go Shield?
I haven't looked at the schematic but my guess is no. The mini jtag is probably wired to the STM chip. Go ports require SPI and GPIO pins which I doubt are part of the jtag spec.
As for a Go Port shield - that would be cool! It would really unify all the products - use any of them with any of the boards you might have. +1 to that idea!
