Nikon is intent on rocking the WiFi on its digital cameras, despite some pesky security concerns with the implementation on its Coolpix P1 and P2 digicams. This new WT-3 Wireless Transmitter that's just gotten FCC approval, however, looks to be fairly substantial, so maybe it won't be so easily susceptible to the same problems. It's also quite a bit more capable, not only wirelessly transmitting photos to your PC, but directly to an FTP server or printer as well. The transmitter will also apparently let you control your camera from your computer, and works with 100BaseTx/10BaseT wired networks if WiFi's not your thing. According to the FCC filings, the transmitter's designed to work exclusively with Nikon's D200 digital SLR, but it seems fairly likely that the same technology could be put to use with other cameras sooner or later.
