I guess I can pipe in here, it works on bins that have been built with shared libs. The "runsocks" script set LD_PRELOAD and LD_LIBRARY_PATH so that this special libsocks5.so intercepts the network calls, does the socks'ification stuff and then calls the libc functions. LD_PRELOAD is supported in FreeBSD 2.1.5 and later. Works prety good on stuff like xemacs reading news through a Socks server to a nntp server. We even have it cleaned up so you can do a "runsocks make" in ports. Haven't got the real audio stuff working yet, but the past couple of weeks have been bad.
