Download RANCID, and you can do something like this from cron:
clogin -c "show ip bgp" router.domain.com | mail -s "Routing table"
customer at customer.com

Depending on what you're doing, "show ip bgp" might be better than
"show ip route", particuarly as "show ip route" might show up internal
routes you'd rather he didn't see.

However, you might be better off telling him to just install
Quagga/Zebra on a Unix box and giving him a BGP feed to let him do
what he likes with. At some point in future you may end up in a
situation where you have or want BGP feeds into your network that you
are not allowed to leak to third parties, at which point the ability
to give him a filtered session becomes a good thing.
