port forwarding?

[Brendan]

I am currently using my home network to access itunes from my imac to my macbook.
1) This works great when i am home, will port forwarding allow me to access itunes from my imac to my macbook when i am at, say a friends house?
2) If not, is there a way to do this?
2) Some songs i can not listen to through sharing, im assuming because of DRM. Is there a way to listen to these songs on my macbook? - Brendan

Try Google

Also, no worries, but try to stay on topic.
