I always think in terms of "Zombie Apocalypse"^TM on what to get myself into.. if its not going to work in that kind of situation then its not worth the time :-) :-) Will "lack of support" mean no binaries provided or removal of the source code so FreeBSD is non-existent anymore on those platforms? -- CeDeROM, SQ7MHZ, http://www.tomek.cedro.info
