No, there are not any for the Rebel line. The EyeFi is your best option, and works well with the Rebels, especially the T1i, T2i and T3i. The newer EyeFi products support saving to mobile devices running iOS or Android, similar to the Canon wifi adapters pushing to FTP. It also can push video and RAW to your computer or to their servers.
The biggest disadvantage is that you don't have the wireless tethering feature that the high-end adapters provide. There are options though, you can look into something like onOne's DSLR Remote, which uses a USB tether to a laptop, and then you use your iPhone or iPad to remotely control and use Live View to frame your shots. This works really well when framing group shots, and you're out in front of the camera arranging the group, or you're actually in the shot. It's also helpful for nature photography, when a IR trigger won't reach because of the sun and you don't want to be near the camera.
