Thanks a lot for the sshd, rkomar - its fantastic to have it.
Because I am running 2.1.2 rc3, and don't know how to root it, I wrote myself a little ssh command line wrapper that allows me to still use ssh in a somewhat 'natural' way.
It needs python to be installed on your host, run it like 'python pbshell.py address', with address being the ip or hostname of the pocketbook (which defaults to pb in my local setup)
