How exactly can I install/use sshuttle under Fedora? It's not in the repositories
I think you can just get it from github either through git
or simply download a recent package and unpack it
And then simply enter the directory and run it. You can move it to /opt/ or anywhere else, where you need it, then hack some simple init scripts or whatever you require.
There is also a SRPM prepared for SUSE and with a bit of hacking probably you can rebuild it on fedora if you feel safer with RPM package.
