At one point we believed that the standard Erlang TCP implementation was 
not fast enough. hstcp was an attempt to get TCP to go faster.

However, recent improvements to our use of the standard Erlang TCP 
implementation have improved Rabbit's performance to the point where 
hstcp doesn't gain anything, so we're abandoning hstcp.

It requires the public umbrella - you can build it like any other 
plugin. But I wouldn't bother.
