I've done this kind of thing numerous times.  Each implementation has 
been proprietary, but really, it's a snap to do.  I generally have cron 
just run the script every minute which scans the directory for fax files 
and faxes them if there are.  I would generally recommend being cautious 
about "locking" (i.e. with lockfiles) files and moving them out of the 
way when they're in-progress so that if it runs long the next cron job 
won't try faxing the same file.  And if you're in control of the 
ftp-ing, generating that lockfile before uploading is a smart thing, 
too.  The lockfile generally stores the PID, so the script should know 
if it owns the lockfile or not.

The sending information is generally part of the specially-formatted 
filename, but you can also store that inside the PDF with PDF tags of sorts.
