 The Underlay maintains a RFC (Request for Comments) series to document our ideas, proposals, progress, and plans. RFCs represent snapshots of thinking and may contain outdated or deprecated ideas. For a more thorough description, see Danny Hillis's [**RFC 0**](https://www.underlay.org/pub/urfcs). Historical documents have been retrospectively mapped into this RFC series with negative numbering (e.g. RFC -2).
