Eh, I don't see a huge problem with Google saying "You can't run enterprise-level servers off of our consumer-level lines" even if they have ridiculous speeds.
"Your Google Fiber account is for your use and the reasonable use of your guests"
I'd consider small-time server software to be within a "reasonable use". If you're hosting a web server with 10 simultaneous requests, you're outside of reasonable use. Any other ISP would have turned your pipe off.
