Craig,
Little hurdle? You continue to ignore how absurdly lopsided home internet service is. Most home internet service is purposely crippled in upload speed to make more bandwidth in the pipe available for lightning fast download speeds.
Your household network can *receive* HD video streams, but your household network cannot *send* HD video streams. Go to www.speedtest.net and find out what your upload vs. download speeds really are. At Michigan State Univesity, I get 30 Mbps download and 14 Mbps upload. At home with AT&T DSL I get 1.4 Mbps download and 256Kbps upload.
It's one thing to upload a few chosen images to Flickr or Facebook, but it's quite another to store years and years of high res digital photos "in the cloud." Streaming an MP3 from a vendor's site is not the same as attempting to upload a 2 GB memory card full of stills and videos even at a blistering 768 Kbps (or less!) upload speed. (At my home speed of 256 Kbps, it would take over 17 hours to upload a 2 GB memory card.)
A household server can accept the files as fast as the household network allows, and can still serve images one at a time to family devices anywhere there is internet access, without having to deal with a third party "cloud storage" company. Will you be able to stream a movie from home? Maybe, if it is compressed enough (ala Slingbox.)
Cloud based backup services such as Carbonite have an advantage in that it doesn't really matter how long the initial backup takes, because it happens in the background, even at 256K upload speeds.

The only numbers that are really important are the peak and average bit rates of your broadband service. Most cable broadband can now stream HD movies; the crunch may come if you have several people in the home trying to access the cloud at the same time.
Bottom line, this is just one more little hurdle on the road to Anywhere, Anytime media. 

Regards
Craig
