funny but impractical
This is a very funny idea and I was quite impressed running it myself. But beacuse of the inherent limitation of ascii based picture, you shouldn't expect this can be your portable viewer.
I've been using this for more than one year for my home-LAN connected to an ADSL line, and it's very stable. My LinuxBox for CoyoteLinux comprises Pentium 75 CPU, 16MB RAM, and the case is made of corrugated paper. :-)
