Could you please describe in a bit more detail what you mean?
Are you saying you want to manage plugins you've developed on your customer's machines (kind of like how Red Giant Link keeps folks updated)?
Are you saying you want to manage plugins you've purchased on your team's machines?
Are you saying you bought plugins and you want to use them on one machine, then move to another machine, etc. without having to activate/deactivate all the time?
Or something else?
