that would be a great idea. Say, you have an
Mathematica Kernel that
does a 3 week symbolic computation and during this time
several Java application connect to the kernel and hinder
it to do it's work.
Your Java application may create a link
and you can take a running kernel and tell the kernel
to connect to the link generated by your Java
