Google Maps API Web Services TOS

I have a couple of questions about the TOS for the "Google Maps API
Web Services"

I'd like to create a notification feature on a website that emails
users and directs them back to a Google map on the website.

My questions are:

1. Can I fetch the driving directions and therefore the driving
distances and use just the "driving distances" in the notification
email as long as the email points back to a Google map for display of
a map and the driving directions from the user's origin to the
destination.

Given this is posted on the Google Maps API Web Services page:

( http://code.google.com/apis/maps/documentation/directions/ )

"Calculating directions is a time and resource intensive task.
Whenever possible, calculate known addresses ahead of time (using the
service described here) and store your results in a temporary cache of
your own design."

2. Can I store these temporary results from the web services to
increase performance when the user clicks on the link in the email and
goes to the Google map on the website?

Thanks in advance!
