Yes, that is an option, not particular impressed with Shutter Snitch in testing (I have an Eye-Fi Card), but I do use it for sync to Aperture using a Workflow. But it's slow and clunky.
I was after a remote viewfinder more than a remote viewer for images already acquired.
Hopefully the EyE-Fi update due this summer that allows for full connectivity to iPhone/iPad will improve that though.
