It's true, there is cerainly quite a bit of overlap between c3 and dsh.

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).

Cheers, Til
