It's true, there is cerainly quite a bit of overlap between c3 and dsh. >From my personal POV, it's just that I know and use c3 for a couple of years now, and don't know dsh very well. The main advantage is probably less typing, as you observed - shortcuts for often used commands (cpush, ckill, ...) and usage of a default group when none is given on the command line. The commands are just slightly more intuitive ($ cexec[s] <command>), no -m or -g option, no '--' before the actual command. The reason why I think it's a good idea to have c3 in Debian, is that probably more people coming from other directions know it already. It's part of the OSCAR installation, and it's recommended in the O'Reilly book on Linux clusters. There is an effort to have a Debian-based version of OSCAR [0], and this package might get this a step further (note that I'm not using OSCAR, so I can't comment on the state or quality of this effort).
