Just a thought though BPL service could be down in case of a disaster so there wouldn't be interference. Possibly at some point they could co-exist. No power no interference. Disaster no Power.
Poor implementations of BPL affect the HF spectrum which primarily utilizes skywave propagation. The problem with poor implementations of BPL is they make it difficult to hear communications coming in from areas further away where the emergency operations are taking place (need to think three dimensionally here).

Amateur radio is not the only users of the HF spectrum, poor implementations of BPL affect all HF users.

I think the BPL scale of economy wil be limited to SCADA for the electrical providers and they will be using BPL in a way that is sustainable for all.

I would like to address the VOIP statement. VOIP is not limited to the National Information Infrastructure or internet. DStar and other links may be configured with redundant WAN routers and hardened RF links on the PHY layer between gateway nodes. Need to think out of the box a little more as it is IP over some PHY layer and although the NIIS is easy, they are other and redundant solutions.

 DStar is cool technology. I thought about using it as part of my counties Winlink deployment (www.winlink.org), however it would eat a big chuck of my ARES/RACES budget, best bang for the buck was the 1.2ghz radios, but that is short range line of site and in my hilly terrain would require microwave links.. too complicated to the KISS environment you try to work with in during an emergency or disaster.. so I went with a TS-2000 and Pactor 3 which will allow my group to stay in touch via e-mail to the outside world with an RF link 600 - 700 miles away to a PMBO in Nova Scotia. I think I would be better off setting up wireless G on Steroid's than DStar from a cost effective perspective.
