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.
Input chunks from the client exceeding the buffer size would get
truncated. Now we communicate the size of the buffer to the webtty and
it will split the input into buffer sized chunks.
Fixes#1.
