I have a few programming classes at school (we're learning Python) where we use rather old hardware. They run Windows XP, and usually they all somehow have a few issues (no HDD at boot, unexpected reboots, permissions errors on user folders, and so on…)
I don't like bringing my laptop, so instead I was using Ubuntu on a live-usb, but sometimes, I wasn't able to download a few libraries (the school seems to be blocking a few URLs). Last time this happened, I X-forwarded a python IDE from home to the school computer from within the Ubuntu Live-USB by SSH, and it was very smooth. Both Internet connections were fast enough to make the experience look like I was using the software locally. From home, my Debian-running computer was able to download all libraries I needed, and any frustration was gone.
Is there any sort of live-usb running linux that has the minimum software required to properly run an X-forwarded SSH session? I don't need a whole UI like Unity or XFCE. Just a Terminal prompt and an X window manager supporting X-forwarded windows would be perfect.
