I did something similar, with a check for the time of day and weekday.
Then I put it in /etc/ppp/ip-up.d. I'm a lousy shell scripter, but this
works:
-------------------------------------------------------
#!/bin/sh

DAY=`date +%w`
HOUR=`date +%H`

if test "$DAY" -gt  0 -a "$DAY" -lt 6 -a "$HOUR" -gt 7 -a "$HOUR" -lt 17
then
        /sbin/ifconfig ppp0 | mail -s IP  user@work.org
fi
------------------------------------------------------
With the "persist" option to ppp, if the link goes down, it'll get
restarted, and you'll get a new mail at work with the IP address.  You
can use a cron job to start/stop the link during working hours.  I used
to use this for transferring files until I hijacked an unused Jaz drive
(my work doesn't provide any remote access 'cause the IT management is
lame.)  If you want to be tricky, you can parse the IP address first.
More trouble than it's worth, IMHO.
