Andy,
Yes, this is something I think OSG will be interested in for distributed, public caches for small (mainly non-HEP) users. What I worry about with AAA and FAX is that we start to use the network more heavily at our larger sites, and create choke points for the odd user. Having a second (and third..) source will help not only the overall speed, it will ensure a threshold of adequate speed.
Sounds like we could get started using the xrdcp-old. Do we have any documentation on how to use it (google only provides me with error reports from 2011).

As for performance, based on old tests you can see about a 5x increase in transfer speed if you have 4 decent sources. Is this something we should move up in the priority scale to get implemented in the new client?
