I have an iPhone 4S with Verizon, and I wanted to know if it would be possible for me to buy an iPhone 5 for the off-contract price and then ship it to my brother in Austria and let him use it there on the GSM network.
The reason I think this might be possible is because the GSM part of the Verizon iPhone 5 comes unlocked.
One obstacle that might stand in the way is if I have to activate the iPhone 5 with Verizon before I send it to him.

Yes, for Verizon phones in the US, neither the month-to-month contract (unsubsidized) phones (when they become available) nor the subsidized phones are in any way carrier-locked.
I tested this by establishing AT&T service on my subsidized iPhone 5 before I did anything with the Verizon side of things and it has worked with both data and cellular provisioning on the nano-SIM from AT&T.
The Apple LTE page will guide you to know which frequencies are available for which model of iPhone 5. The model of each phone is conveniently printed on the back plate of each device.
The carrier you intend to get service from is in the best position to guide you in picking a US model to import, but Apple's documentation show no difference in the GSM 3G capabilities of any of the three phones available at launch, namely the A1428 (GSM), A1429 (CDMA or GSM).
