Yes, unallocated sp goes into a booster.
Size of booster is determined by your warbarge module level.
Takes 2 days to produce.
You sell it.
New owner plugs it in and full amount of SP in implant becomes available after 1 day.

Not really fond of the idea, sorry.
SP is (and should remain) character specific.

What stops someone from making 50+ PSN accounts, accumulating SP and transferring it to a central account in order to have a perma-booster on their main?

NO

Setting the module far enough down the warbarge progression path. If you put it in the sixth slot it would take an exorbitant amount of money to pay for all your alts to have that module unlocked. Grinding that many alts to have your sixth module unlocked to level 5 would simply be unfathomable.

Skills after a certain point really don't have a pressing significance. Sure, you may have more play-counterplay options at your disposal. This system of incremental skill transfer incentivizes player recruitment into dust as one player can support the initial push of a new player to get into important skills that help make them more competitive--taking once what took weeks and month into a couple days. If the new player screws up they have a respec token to sort things out anew. Yes, this does run counter to some of the entrenched principals of CCPs EVE Online, but we're trying to grow numbers with this Dust.

For what reason should it?

Even if the SP tokens work exactly like normal Boosters (I.e allow players to manufacture Boosters) I think its a bad idea, since it would severely cut into AUR booster sales (which I think is still the most lucrative business CCP have at the moment)

You're not killed by skills on the skill tree. Even if you had a maxed skill tree it does not guarantee you are going to be any better at defeating an enemy in combat with say 10m SP

For sake of clarity.
Implants = the sp units you are extracting
Boosters = modules you buy from current NPC market

This was also clear.
What I am basically against is the speed the implants release the SP (1-2 days?). This would mean if I have "a lot" of ISK I could technically buy many A grade implants and unlock millions of SP in a very short time (compared to boosters). So if you spend a ton of real money (to get the ISK), you can jump ahead a person who played for years (and even payed AUR for regular boosters).

Even if you make the implants release the SP as slowly as normal boosters (thus addressing my concern above), it will eat away from the normal booster sales which CCP relies on for the continuous support of the game.

But yeah, from a lore perspective I see nothing againt it.
On a business perspective though

This discussion is interesting , I wish there was a way to move existing SP's of a player to another as well but I wish it could be done like this :

I create an alt character and wasn't happy with my main , so I transferred my SP's from my main to my alt but by doing this I would have to delete my main character after the SP transferal .

It's like a race / name change if so desired .

Your idea is interesting though .

This actually sounds awesome.

Hypothetically speaking, if I had connected 16 PSN accounts to Dust and activated all 3 profiles on those accounts, I'd have 48 profiles collectively totaling 816 million skill points. I have no problem killing those accounts to transfer SP.
Could loyalty rank be the factor which prevents me from transferring those skill points to anyone? Loyalty rank is heavily influenced by AUR at the moment so this could become a contentious point for players.
