We had exactly the same problem in Amsterdam, untill El Presidente
(momo) explained the mechanics of capitalism to the isp/adsl companies.
He reminded them that their goal waas to earn money, and if he would pay
for his connection, even though it's in a squatted house, this would be
according to the business plan of the adsl company... Worth a try.

Wireless could be an option if you have a direct line of sight between
the place needing internet and some place that has internet. Remember
though, normal UTP can be pulled up to 100 meters no problem, 200 meters
if lucky...

The wireless stuff we use is mostly straight from the shops:
- Normal pcmcia wireless cards, _with_  antenna connector at the back.
  (With and wothout are available. Often the ocnnector is hidden behind
   a little removable plastic cover)
- laptops with pcmcia adaptors, or pcmcia-isa adaptors.
- pigtails (thin breakable white cables that fits in to the back of the=20
  wireless card and fits into N-connectors, used for antennas. These
  _should_ come with the pcmcia card.)=20
- antennas (to boost range up to 2 km)

I put some images of equipment lying around, available on:
http://krutt.org/wireless/
(no pigtail here right now unfortunately).

Always start experimenting with the machines next to each other. When
you have a working connection move them apart and see how far you can
go.

Point-to-point antennas can be built by yourself. Se fx:
http://verma.sfsu.edu/users/wireless/pringles.php
http://www.wireless.org.au/~jhecker/helix/helical.html

But for long range connection you might want a commercial grid antenna
orso. Example:

But whatever you do - you still need an uplink to the internet
somewhere...

I'll try to dump all this information and more into Blicero's brain when
I see him in Firenze/Florence November ;-)

feel free to mail me questions, setup problems etc
