## プロジェクトの歴史と使われ方

rmcast packages RML, the Reliable Multicast Library, a free software library for reliable data transmission over IP multicast.

### プロジェクトの歴史

The official archived project page explains that IP multicast saves bandwidth by sending one packet across each physical link, but that UDP-based multicast lacks reliability. RML was developed to provide a reliable multicast environment and was distributed under the QPL.

### 採用の歴史

The project appears to have been a niche academic and systems-networking library rather than a broad user-facing tool. Homebrew packaging keeps the library and the `mcastproxy` and `rmchat` executables installable for legacy multicast experiments.

### 使われ方

Package-level usage centers on the reliable multicast library and the shipped command-line programs `mcastproxy` and `rmchat`; the official project page says the release tarballs included a manual.

### パッケージ好きにとっての重要性

rmcast is notable to package maintainers as a preserved multicast library with old release tarballs, bundled manual material, and QPL licensing. It represents the kind of specialized networking code that survives mostly through Unix package collections.

### タイムライン

- 2004: Version 1.5 released on 2004-09-26.
- 2005: Version 1.6 released on 2005-12-14.
- 2006: Versions 1.7 and 1.8 released.
- 2008: Version 1.9 released on 2008-05-01.
- 2009: Version 2.0.0 released on 2009-08-06.
