I see where your coming from.
It would be nice to have a wifi cartridge for the c64, certainly i would buy as long as it's remains RRNet compatible.
Only it would need to be some kind of hardware bridge between a RRNet type Ethernet Nic and a wifi ibridge i fear.
due to restraints inherent when dealing with a 1mhz 8bit computer.
What I have in mind will not be compatible with the RR-NET, although I intend to make an ip65 driver for it, and a version of the KipperKart API.
As mistermsk points out, it is already possible to connect an RR-NET device to a wifi bridge, and get a wireless c64 that way.
Current state of play is, I have found the ZG2100 wifi chip, which has an SPI interface. The docs for the chip itself don't seem to be publicly available, but there is a TCP/IP stack (with C source code) for the PIC that includes drivers for the ZG2100, so it should be possible to work out from that how to do the important things (i.e. initialise, select an SSID to connect to, set encryption mode & key etc).
There are also at least 2 breakout modules that include this chip, e.g.
http://www.futureelectronics.com/en/tec ... 136-2.aspx (for PIC) or
http://www.asynclabs.com/store?page=sho ... egory_id=6 (for arduino) - approx $55 which seems reasonable. Both of them are for specific MCU dev boards but I expect it will be possible to hook them up to a generic SPI interface without too much effort.
I've taken a punt and ordered on of the PICtail boards. Once I get it, my plan is to experiment with the SPI interface using my bus pirate and some ruby scripts - If I manage to work out the necessary incantations to get the module talking to my wifi network that way I will attempt to hook it up to the SD port on my MMC Replay and have a crack at an ip65 driver.
