Query: EMFS: Repurposing SMTP and IMAP for Data Storage and Synchronization   Cloud storage has become a massive and lucrative business, with companies
like Apple, Microsoft, Google, and Dropbox providing hundreds of millions of
clients with synchronized and redundant storage. These services often command
price-to-storage ratios significantly higher than the market rate for physical
storage, as well as increase the surface area for data leakage. In place of
this consumer-unfriendly status quo, I propose using widely available, well
standardized email protocols like SMTP and IMAP in conjunction with free email
service providers to store, synchronize, and share files across discrete
systems.
