It has to be a CD-RW, the CD-RW has to be in UDF format, and the host
machine has to be able to read and rewrite CD-RWs in UDF.  This is
actually not that tough to arrange--it just has nothing to do with
PHP.  'DozeXP should be able to do this, and Linux will do this if the
right kernel options are on.  Don't know about OS X.

OOO Calc, which should be just fine for basic tasks and is Free.

UDF, which has been a standard for quite some time, allows this.  The
main thing you lose is some space on the CD-RW.

It sounds like whoever defined the requirements was trying to solve a
problem in the wrong way.  Why drag physical media into this when you
have the Net available?  And if the clients don't have the Net
available, *why not*?
