Instead of using a seperate ospf process, why not use a
seperate router just to run OSPF between you and your customer.
And that router can potential buffer for potential OSPF trouble.
between yourself and the customer.

ie

Your Network Router <--BGP--> DMZ Router <--OSPF--> Customer

I can't think of other name to call that Middle Router.
