>> office -> /mnt/owfs/12.0AB668000000/PIO.B
>> bedroom -> /mnt/owfs/12.A97F68000000/PIO.B
>> living -> /mnt/owfs/12.FEB568000000/PIO.A

>> Well, your basic problem, readable device names, is easy in C.
>>
>> Use macros:
>>
>> #define OfficeSwitch 12.0AB668000000
>>
>> This isn't as usefule if you use several of the programs at the same time.

>> and owcapi).
>>
>> I've thought of adding aliases to the underlying configuration.
>> 1. They would probably be listed in a configuration file
>> 2. We would have to decide if they are persistent, or can be changed on
>> the
>> fly.
>> 3. We'd have to decide on handling of ambiguous names: deadbeeffeed,
>> interface,
>> uncached
>> 4. Would directory listings show the native names, or the aliases?
>> 5. Are aliases for devices that are not currently on the bus shown?
>> 6. Are aliases unique? How is this enforced?
>> 7. For a program linked to an owserver over the network, where is the
>> alias
>> kept? In the owserver directly connecting to the device, or the calling
>> program?
>>
>>
>> My first pass at an implementation:
>>
>> A property of "alias" for every device, with a default of empty. A
>> non-empty
>> alias is used in preference to the native device name.
>>
>> No enforcing of uniqueness is made, and which duplicate name is matched
>> is undefined.
>>
>> Alias can be set on the fly by writing to an alias property, even if the
>> device
>> doesn't exist.
>>
>> There is a property under settings that shows all the current aliases,
>> suitable
>> for populating a configuration file.
>>
>> Clearly the implementation becomes messy, which is why I haven't
>> implemented
>> in in the absence of a strong demand.
