distcc is a program to distribute builds of C, C++, Objective C or 
Objective C++ code across several machines on a network.  
distcc should always generate the same results as a local build, is simple 
to install and use, and is often two or more times faster than a local compile.

distcc by default trusts its clients completely that in turn could
allow a malicious client to execute arbitrary commands on the server.

For more information about DistCC's security see:
http://distcc.samba.org/security.html
