Hey guys
(to moderators; please move this post if you think its in the wrong section... sorry i wasnt exactly sure where to put this)
Just a quick question; the other day while watching a bit of TV i saw a Windows 7 advert (the "Windows 7 Was My Idea") but it talked about this guy, who was in spain and wanted to view his videos from his computer in the UK. And he was just using a laptop + the internet to 'stream' the content - just it didnt tell me
HOW this is done, not even what the feature is called

.
I would really benefit from this, as ive just brought a laptop for use at college - and would find it great if i could just 'stream' my music collection from my harddisk at home. Thing is, i know how to do this with an internet-LAN (Hamachi) - but that must mean my computer at home must be on while im streaming - and that just isnt going to happen. So this advert appealed to me, coz it seemed to show off a feature that i could use - im guessing it stores the information somewhere? Im not sure....
If anyone knows of either what this advert was advertising... or... a programme/way of being able to stream my content without using a form of 'always-on' LAN.
(before you recommend such streamers like Grooveshark & Spotify - i cant do this as the college hotspot, blocks both programs from streaming
- bloody websense)
