FreePhone (URL: http://www.inria.fr/rodeo/fphone/) is supposed to be a
workable tool and is supposed to be able to work under Linux AND
Windows. Mac users MIGHT be able to tweak the source code to
work under MacOS (If they are using PPCLinux or MKLinux, they'll be
able to use the software directly). As far as I'm concerned, we should
be using compatible tools where possible.
