ESP8266

Has anyone thought of using one of these on the CPC to give it WiFi?  Although I suspect it wouldn't be as good overall as the M4 board, it is a little bit different with 4mb onboard also at around AU$5 per board.  Likely it could receive files really fast into it's own memory but you'd have to use I/O to transfer it to the CPC - apparently not really fast too.

It uses the same chip that the M4 and other CPC WiFi solutions use. What do you expect this board to do differently?

It has 16 GPIO. With 160 MhZ, I am wondering if it would be able to "sniff out" an IO address from the Z80 address bus, and when it arrives, immediately switch over to sniff out the data on the databus as well... anybody tried that? (And, are the GPIOs tri-state? I guess so. No experience yet with ESP. Would be good if somebody tried that - they are so damn cheap and fast and versatile.... I believe in M4 case, ESP is only a "slave" and not directly connected to the CPC's address and databus, I believe this is done by the ARM, right?).
