What I think Dropbox's next move should be.

"While most of these addons are simple services glossed with a thick coat of wax, Dropbox is a real benefit and definitely would be worth a line on my bill."
If something's actually worthwhile and not a gimmick, it likely won't work. We get gimmicky commercials demonstrating people being impressed that they get to spend "only" $99/month (for up to X months!) to get "unlimited phone, cable AND internet! (restrictions apply)" service. Or "choose which 3 of our 4 services you want - you've created a custom service plan! w00t!" commercials.
All of these serve only to let them continue to ride the gravy train of massive markups ($40/month for a voip line which doesn't include non-US calling?) and lock you in to future price hikes. I can't recall any service an ISP has ever offered me that had any real benefit to me as a user. I don't want your crappy webmail, I don't want your embedded virus scanning on my PC, I don't want your 5 meg webspace.
A branded dropbox or carbonite-style backup service included at a reasonable price? That would smack of real value - current mega-ISPs would run a mile (or a kilometer) from that one.
Dropbox ISP integration would encourage loyalty, not profit. Cookies wouldn't do the same. But since you bring it up, Netflix could offer a similar service to cool off the cable companies, making the headaches Netflix's lawyers have to deal with a little less troublesome.
What about 4 people sharing one Internet connection at home, all with their own Dropbox account? What about someone that doesn't have an Internet connection (and who access Internet at school, libraries or their friends places)? And what about company Dropbox accounts?
Personally, I use Dropbox instead of the "Telenor Online Backup"-- and I can't say that the billing method has made much of a difference.
I also think Dropbox's own support system far surpases the support that most ISPs have for personal web space.
Do not try to integrate into the billing system on Canadian ISPs, I have experience with two of the major providers and it's a nightmare to say the least. I managed to find $3 million in revenue with a couple perl scripts and the expect module. Let's just say you're dealing with operating systems where TCP/IP is optional.
If you really want to pursue it drop me a line, I may be able to put you in touch with the right people.
