In addition to my day job I also run IT for a 501(c)(3) ham "club" that does amateur radio based public service and emergency communications. Our annual cash donations are about $100. We could never afford an IPv6 allocation or an AS number. I wish we could because I'd love to use some of the AMPRNET space for some of our operations. Our ISP doesn't support IPv6 yet, so I won't even get into that discussion.
While we don't have cash, we frequently get donations in the form of [used] equipment. Our entire network backbone is Cisco. Our radio systems are almost exclusively Motorola public safety grade hardware. Our Internet connection is paid for by a served agency. People are happy to donate their time, services, and hardware to us; just not cash. Saying that not having cash on hand means you don't have the resources to do packet radio is not necessarily true.
