Does anyone have a film recommendation that links cooperative business and community to telecomm industry / Internet / broadband?

This really is highly specific! This likely isn't what you're looking for — but I want to mention it here anyway since you've gotten such sparse response. http://www.tcm.com/tcmdb/title/95377/Western-Union/, a 1941 Western made by Fritz Lang that revolves around the construction of the telegraph system. Again, probably not what you're looking for as it's very much pre-internet and about 'cooperative business' only insofar as it concerns several different parties variously collaborating on and sabotaging an epic telecomm project — but perhaps you'll find it interesting.

Thanks rhizome and bubukaba, at least your suggestions may be jumping off points. I'll check them out this weekend!

I've been thinking about this question all weekend. The first two examples I thought of -- http://www.ntca.org/about-ntca/history-of-rural-telecommunications.html and http://www.arrl.org/ham-radio-works -- are pretty good examples of telecom projects resulting from people joining together for the common good, but finding films -- either fiction or documentary -- that deal with either of those is pretty tricky! However, there was some press coverage of http://www.wqrz.org/mambo/index.php?option=com_content&task=view&id=31&Itemid=55, a Mississippi non-profit community-supported low-power FM station (itself an outgrowth of the emergency ham radio initiative in the area) that famously was one of four broadcast stations to stay on the air after Hurricane Katrina (out of 41!), and became an invaluable lifeline to people in the area (to the point that the FCC authorized an unprecedented emergency power boost for the station, and FEMA distributed radios pretuned to the station's frequency). Bill Moyers' Journal, a PBS program, devoted a http://www.pbs.org/moyers/journal/08242007/profile3.html to WQRZ (and the http://www.pbs.org/moyers/journal/08242007/profile2.html and other stations like it). The http://www.pbs.org/moyers/journal/08242007/watch2.html is available as a stream from PBS, and WQRZ has posted a copy of the 22 minute WQRZ segment http://www.myspace.com/video/wqrz-lp-103-5-fm-bay-st-louis/wqrz-katrina-radio-on-pbs-bill-moyers/3535919. There's also a http://www.pbs.org/moyers/journal/blog/2007/08/_lowpower_fm_radio_share_it_wi.html about the station on the Bill Moyers blog, as well as a http://prometheusradio.org/node/2578 of the station from Prometheus Radio.

We've received permission for a one-time screening of a new film called Industria Argentina. not exactly telecomm/internet/broadband topically, but relevant to the cooperative subject area, and we have a local community member with experience in Argentina, so we're going to expand the focus a bit it appears. Thanks again for the recommendations.
