For card sharing, the person with the original card will need a phoenix programmer (which the card is placed in) connected to pc running a card share host, and all others wanting to share the card (including the person with the original) will then need a season card emulator plugged into a pc, with card share client software. Broadband internet is probably better than a modem I would have thought. You need some friends to set up a card sharing group - it has to be a highly trusted group!

Alternatively, you could all buy dreamboxes!
