But how is this new? That's always been true, hasn't it?

It's new because it runs on a far smaller machine than is normal for a root server. They are talking about running a root server on a 1.2Ghz Athlon with 1.5GB of RAM. Up until they dropped the hardware config from their site, ISC's "F" root server used to be run by two AlphaServers, each with 4 500mhz CPUs and 8Gig of RAM (website now says it's up to 4 machines, but doesn't specify what hardware).
If you look at the comparison page for the RS-DNS server though, it looks to me like they've simply done away with the BIND text-based zone files and implemented their own (probably) binary zone files.
Text is nice for us to look at, but it's slow for a machine to parse and takes up far more room. For example, an IP address string of "192.168.12.32" is 13 bytes long, and for a machine to read, has to be carefully parsed for dots, numbers, and to ensure the numbers are in the correct range. If you didn't mind it not being human-readable, you could easily compress it to 4...less than half the size, 1 byte for each number. It'd also have the bonus of doing away with the parsing and checking, as a byte has a max range of 255.
