| This is a collaborative editing protocol I came up with. Like OT, it | |
| is change-based, not diff-based. But it is much easier to verify that | |
| clients end up converging, because they all end up applying the | |
| modifications in the same order (so that they _have to converge_, if | |
| they are using the same algorithm). | |
| Clients start with same version + version number | |
| When a client makes a change, that is locally applied and a description |
