Network accessed Arduino Display Board

Hello all,

I am a general novice with arduino, having a few college courses under my belt. What I want to do is create a network accessed arduino display board that I am able to communicate and send messages to from anywhere with internet access. I am going to be in South Korea for a several months this summer and thought this would be a fun gift to give my girlfriend as she isn't too happy with the long-distance thing. (Getting me out of some hot water)

This being said, I would like this to be a plug and play type thing where she doesn't have to worry about messing with her router settings or dealing with the arduino code. I found multiple ways that this would be feasible at the links below:

The most reasonable option, it seems, is using a X2 gateway to connect an xbee module to the internet, but this would require a lot of configuration on her part. Another option is port forwarding and using a DynamicDNS. However, she will be renting an apartment and may not have access to router settings. I guess my question is, "Is there any feasible way that I can send messages from South Korea to an arduino to be displayed without altering router settings or a large amount of work on her end?"

Any help is appreciated!!

Yes, but probably not the way you expect it. Forget everything that uses radio frequencies, connect it by Ethernet and use a server in the internet to route the messages. That way you have the work and the costs (renting a server on the internet) but she simply has to connect it to the router by a cable.
