This may be practical for small payloads, perhaps even in vast quantities, but is ludicrous for larger endeavours. My (long overdue and unfinished) sci-fi story, /s/BittersweetSeeds, addresses the payload issue (among others) with a combination of the best solutions I've come across, as yet unseen elsewhere, together in a completely new and unique way, wrapped in an engaging dramatic cautionary tale. I aim to work on it this winter - and a new contemporary anti-cyberpunk story.
