Here's what he said.
To answer the question, yes, you could. We probably don't want that though. That would mean that all chunks with a portal would have to be loaded at all times, for all players.
And a sole chunk may not even be possible to load on an individual basis, so it may have to load all the chunks that all the other players are.
I think the portals manager needs refactored to be more in line with the FireManager, and allow distribution through that way
