Blocking port 25 is not really necesary. The same net effect can be obtained with most ISPs implementing spf (http://spf.pobox.com/)in combination with Domain-Based Blacklist Zones. This way most zombies will be prevented to send mail (since receiver's server will likely block them).
For Internet access is even worst, since in poor countries comunications costs are enormous. In Romania, for example, a dialup connections kept always on costs 300 USD, while minimum wage is 15 USD/week (excluding taxes). Fortunately for just learning high bandwith and full-time access are not required (and may be even counter-productive) OTOH, computers can be have much cheaper. A new, entry-level system goes for about 400 USD (with monitor and networking). Software costs are kept low either using Linux or (ever popular) unauthorized copies.
A new model will have to be approved for use again, a expensive and time-consumming process. By using the same name vendors may get away without doing it. Doesn't look very legit, though.
In fact OOo doesn't have different programs for each task; Write, Calc, Impress are just shortcuts/symlinks to a single executable, soffice(.exe). So it doesn't matter much what component you have opened; it's the same program running.
It's simple for ISPs to receive mail on the machines they use to send mail; they may just do NAT or port forwarding for port 25 to the actual receiving machines. This can be done at the router, no server modifications are necesary. So we may start only receiving mail from IPs that are listed as MX for the sender domain, and have a valid reverse DNS name. ISPs that don't follow best practice can be automaticaly notified ( at the address block admin contact address for example) by the MTA, and their mails can be subject to agressive filering and/or temporary rejected for -say- a day. Also their upstream providers and/or registrar can be automaticaly notified also, as they may have more leverage to get things fixed. To keep such notifications managageable, they may be agregated/sumarized for a period of time -say one day- in a single message.
It may be a reaction to US efforts to impose this stupid software patents sistem on EU. Right now, in EU software methods aren't patentable, being only protected by copyright (as it should be in a sane society). But US, WTO and EPO are pushing to change this (more on http://petition.eurolinux.org/). If BT put "modest" charges on hyperlinks (ex. 5 USD per hyperlink, plus a 0.35 USD royalty per every hyperlink usage), the perspective of distroying the US Internet as is today may wake up US legislators to stop backing a stupid concept. The Internet will survive anyway in the rest of the world, which doesn't honour US patents (yet). Nota Bene: This may not be the last such case. If the sistem remains in place, we'll be allways at the mercy of such claims.
As signaling is done in analog domain, all communications are done throught modems (unmodulated digital signal can only travel a few meters). So, ISDN, DSL, cable, fiber, all use modems.

Costs the exact same price as a typical blank hard disc
I'd like to know where I can find 5$ CF ATAPI adapters. So far I found them at about 20 $

MAC addresses must be unique in order for APs to work. So 00.00.00.00 may be a bad idea if somebody else do the same.

Unfortunately this may cause trouble with the ISP, as such usage may constitute theft of service (pretty much as with cable TV).
