Regarding the development on Twitter: Funimation only own the rights in the US. If we're talking specifically about DVDs and Blu-Rays, yes I believe Funimation do own the rights, but Funimation have no bearing on TV airings at all.
In case IPPTV is as inactive as it looks, I suggested she try asking the actors. While they are of course just actors, they would hopefully be able to grab her an E-Mail address or something so she can talk to someone at Ocean about getting this. Granted, that may not be necessary, but it looks like she's seriously trying to get this on the air, so I really want to make sure she has all the available information she might need.
Also,
holy crap, this might actually be happening.
Regarding the Ocean vs Funimation thing...
Sabat and McNeil are fundamentally different approaches to the voice; same with Sabat and Drummond, the various Ocean Gokus vs Schemmel, and many other voices. Although I have been vocal in the past about my preference for the Ocean cast, and my distaste for several of the Funimation voices that remain obvious impresonations of the Ocean cast, it's an entirely opinion-based thing.
Naturally, I'm firmly of the opinion that McNeil gives the better performance, largely because he's a much more seasoned, experienced actor than Sabat, but Sabat's version is a cool alternate take on the character; much more of the zen, wise master Piccolo emobodies later on, rather than the darker demonic Piccolo you'd probably think of as being him from earlier on(Although I've always loved how McNeil kept the darker undertones of Piccolo even once he'd mellowed out much later in the run).
Ultimately, both versions are valid, and just bashing one version as being strictly worse than the other is not the right way to go about this. As it is, we currently have the Japanese cast, the Funimation cast, the Ocean cast, and the Blue Water cast to enjoy(As well as numerous other non-English dubs). Rather than picking one as the definitive one and bashing all the others, why not just enjoy what's good about each of them?
Of course, the Ocean cast being the less well-known one in the US, that's the one that's bashed the most, which really sucks for us Ocean fans.
But, I guess that's the internet for you. ¯\_(ツ)_/¯
(Of course, I'm far from the authority on all this; I'm definitely biased towards the Ocean dub)
The point of Dragon Ball is to enjoy it. Never lose sight of that.
