But yes, you can shoot without having a card if tethered to a computer. You can control all settings of the camera via the EOS Utility software.
Likewise - no bent pins on my Canons yet (dating back to 2004).
Besides shooting from the camera, if you can get the pins gently bent back so you are able to put in a CF card, then put in a big card (8 GB or 16 GB) and use a USB cable to dump the photos to an external device periodically. There's also a wifi attachment for the camera, not sure whether it supports all functions or not.
