16x24 LED Matrix on RasPi?

I'd like to chain 4 of these and use them with a RasPi since the arduino is not able to handle SSL (I have to fetch data to display using SSL).

How are chances? Are you already working on anything related?

We don't have any software or libraries for the Raspberry Pi "in the oven" at the moment.

Depending on your comfort-level with writing the low-level bitbang-y stuff, there's no reason why this shouldn't be possible in principle...the interface is a simple SPI-like thing. The voltage levels are different, so just watch your step there, but usually there's not a problem talking to 5V inputs from a 3.3V device.

Some Raspberry Pi GPIO tutorials have been popping up lately.

I usually don't hesitate to write a kernel module or some c-code to get it working with /sys filesystem, but in this particular case I have not enough time and would like to use the library functions from ardafruit. Thanks for the links, I'll think about getting in between the lib and maybe /sys for gpio.
