Hi, there's a new octopus distribution at http://lsub.org/ls/octopus.html It can be used, for example, as a way to use a remote Plan 9 machine using any other system as a terminal.
The main tar ball includes Inferno with a pre-installed octopus and a installation script so that it should be trivial to install and use it. A tutorial can be found linked from the url above. Programs included like omero, olive, oxport, etc. may be used without using the rest of the octopus. Also, a set of Plan 9 programs for use with the octopus are available as a separate tar ball from the same url. This includes mouse redirectors among other things. Enjoy
