ok. so heres the run down. i have a rather large media library on my home computer. (iMac) i want to be able to access those files from anywhere i have an internet connection on my MBP. if im sitting in the park cruising the interwebs. i want to listen to the music i have at home. if im at school during my down time between classes. i want to listen to the music i have at home or even watch one of the episodes of House MD i have on my computer. is this possible? can i do it for minimal cost? what do i need? i have a Netgear WGT624 v4 router if that matters.
