Then how about:
- `disabled`: `boolean` - set to `true` if the RTPEngine was disabled by an RPC call
- `active`: `boolean` - set to `true` if the module is actively using this RTPEngine (i.e. the internal `rn_disabled` flag is set to 0). This will be always set to `false` if `disabled` is set to `true`.
- `recheck_ticks` : `number` - ticks (seconds?) for the next recheck if the RTPEngine is both not active and not disabled, otherwise 0
Sounds good. Perhaps use -1 as recheck ticks for a disabled instance? Zero could be a legitimate value.
