The Pain · Narrative

You are a freelance video editor who constantly needs to send massive, multi-gigabyte project files to clients for review. Email attachments are impossible, and traditional cloud drives are either too expensive, too slow to upload, or require your client to navigate clunky interfaces. You want a simple, professional-looking web link where clients can download the file directly from your local machine securely. Existing command-line tools are far too technical for your clients, and local-network sharing apps fail because your clients are in different cities.

Why This Might Fail

Self-rebuttal — the most important trust signal

  1. 1Strict corporate firewalls on the client side might block WebRTC connections entirely, leading to failed transfers and lost trust.
  2. 2Users may find it too inconvenient to keep their browser tab open and computer awake while the client downloads the file.
  3. 3Incumbents like WeTransfer or Dropbox might increase their free tier limits, reducing the immediate need for a P2P alternative.

Evidence Summary

How AI synthesized this insight — no verbatim quotes

Multiple developers highlighted the frequent need to transfer massive files to peers across different geographic locations. They praised the combination of a self-hosted backend with a zero-install browser frontend, noting that existing command-line solutions are inadequate for non-technical recipients. The discussion strongly validates the demand for a seamless, cross-network file sharing mechanism that bypasses traditional cloud storage limits.
