user19323: How can addresses be exchanged practically & efficiently between two users?
Visually copying & keying them is impractical & faulty.

user2306: Very true! Manually copying a 34 character address is no fun.
You have three major options:

QR code. Print it out in advance.
Create a FirstBits address.
Bring your phone, and load a client that supports NFC.

By the way, if you enter someone's address wrong, the Bitcoins won't send - Bitcoin addresses have a checksum built in.
