When searching their online whois[1], they'll tell you if a domain is for sale and link to the for sale page. They don't use any of the info you put in the DNS though. The URL comes from their internal system. You need to register it separately. They also don't use the price, txt or anything else you put in the DNS.
All they use is the "fcod", to look up the url in their own system. They had a different syntax for this before, but this functionality has existed for some years.
As a side note and you're probably not interested in this, but since you mention the total size: your avatar/favicon can be compressed down. to 14.3kb (saving 18,6%) which keeps the Toal just under 50Kb!
One other thing to consider is the fact that sleeping less means you've got more time to spend, also during hours when almost nobody else is awake. For some this isn't an issue, but for others this could prove to be difficult. I for one would opt for an Everyman cycle, since it allows you to be awake during relatively "normal" hours.
How do they handle chargebacks/failed payments and do they charge their merchants for failed payments/chargebacks?
I think direct debit could be huge on mobile, but given the fact that every direct debit payment can be cancelled within a month or so, how do you reduce your risks?
