[RFE] lshell

hi, is there is a way to implement the lshell (http://lshell.ghantoos.org/) which is a limited shell ? this could be a security enforcement by limiting the number of available commands.

Here an example of a basic configuration :

[global] logpath : /var/log/lshell loglevel : 2

[default] allowed : ['ll', 'cd', 'echo', 'passwd'] forbiden : [';', '&', '|', '`', '>', '<'] warning_counter : 2 aliases : {'ll':'ls -l'}

More, it is possible to limit the access to some directories (chroot like ;-) ) Disconnect after a certain time etc ...
