A functioning network? There have been many forks now in history, one that made btcpop unusable. I have similar problems with other PoS coins, colx for example. From time to time you find yourself on different chains, this is not yet a functioning network.
I disagree (maybe). I've have been here a long time, and have been through most if not all of the forks. Tranz has addressed all of them. The last one was before the POW ended. I appeared someone - I believe it was the Hash 2 Coins pool, broke off on a different chain, because of the hash. They never got their wallet back running and dropped HBN from their pool. I noticed the fork, and reported it to Tranz. Consensus was formed around the Chain that most of us were on, which was the same chain as Cryptopia. Now that HBN is 100% POS I don't expect as many problems. I don't know exactly what you mean by "time to time" - but it's been acceptable.
I think if a charity needed to move funds, or have a multi country currency and decided to use HBN. It could work. They would get the benefit of the blockchain, and the charity staking. What do I think the odds are - IDK 1:1000, 10,000?
If you are on the correct wallet peers and sync times are good.
HBN is a good low cost, stable, POS coin, with a charity niche
