Contact information by reference

It would be neat if Sandy could remind me of contact information when reminding me about things relating to specific contacts... Perhaps better explained by example:

"Remember Jon Doe wants to meet on monday"

When Sandy reminds me on monday, she would also send me Jon Doe's contact information (if available), as if I had sent a "Lookup Jon Doe". Maybe this would need a special syntax, or Sandy could intelligently find contacts in commands like the one above.
