Viability of VC with the current engine

If there was ever an intention to add voice chat into Zero-K, would it be possible with the current engine and its limitations? Could it perhaps exist as a mod?

I've used it only a couple of times before. Sadly, that one clan doesn't cover most ZK players so I'd only be speaking to a limited few. If ZK ever used VC I would imagine a whole team-wide voice channel instead of one for just a single clan.

My question is still targeted at VC built into ZK not using external apps
