> Larger and larger block sizes are important. LDPC probably is the more practical methodology today, though I admit that I'm ignorant about them. Still cool to see someone try to push Reed Solomon to such an absurdly huge size though.
Multi-dimensional RS codes are an easy way to get to an absurdly huge size for real (granted they stop being MDS). Long term archiving is an obvious application. One-way communication, like in deep space, is another. Though, speed requirements are less demanding there. That one tried to push the envelope for a one-dimensional RS code to those limits is a curiosity. Some techniques may be useful in other practical approaches. It's a pity the code representation had to depart from GF(2^n).
