It's been a sort of a remote inspiration :-) A major problem
with it (besides the security stuff listed on Wiki) is that
it's implementation is in-kernel, and as such can be used
directly only when the OS has the implementation. There is no 
way to write a portable application with it.

Other than that, I'm proposing an opposite approach: why bother
about reducing the cost of the initial connection, if we can
instead just open the connection once and then keep it open
for a very long time at a low cost?
