Launch an Xspice and run:
echo -ne "\033]844;127.0.0.1;9876\007"
This will launch a SPiCE client connecting to 127.0.0.1:9876.
Still need to add all the security stuff and generally be
more defensive in the implementation.
Since xterm and hterm do not have proper comments for their license,
add license-loader to keep their license information in the minimized
bundle file.
