Currently there is no shell like xterm available on AmiCygnix, sorry.
But if you wait a little bit, you can use my special AmiCygnix version of python, which includes for example pyGTK. There is a python console implemented with pyGTK:
It will come with an update of Gimp and Gnumeric for python plug-in support. Both apps offer an own python console.
Don't know, if I should publish a separate package.
BTW: xlaunch is only a little helper tool. You can - for example - launch an amiga command with an unix path argument. It is no shell.
