/ From what I've gleaned from this list, if you create a mapset with  
/multiple layers, each layer *has* to have a different Family ID.

I'm not so sure about that.
As far as I understood it has to have diff FamName, & FamID if you want
to be able to switch it on/off, but if you only want it loaded as one
map it should work OK, I think.
But I have not played with it enough yet.
With the --index option it now becomes possible to send families via
mapsource to the device which was not possible earlier. At least not for
me.
But some people seems to get selectable maps from this, while I cannot.
Maybe the first step to 'fix' this will be to reach consensus on what is
broken?
If some gets it to work, how do they manage it. Do I use all the
neccessary options in my approach, is there certain options that fouls
it (there was mention before that family-id did not work / messed
something up, but that seems to have been fixed), how much of the
failure / success hinge around the device model /age?
For now I would prefer the skills to be concentrated on the address
search function so that I can drop --road-name-pois ;D But that's only
me. And maybe address search will depend on being able to send the maps
successfully to the device? Not neccassarily multiple maps, but
definitely the mdx mdr etc.
As a start can we try to find out from those who has been able to send
multiple maps to their devices successfully / with partial success / no
success, what mkgmap options they used, what send methods they used,
what gps device was used, what results they achieved?
Will this maybe start an efficient investigation without involving too
much of the programmers time initially. Will it help the programmers, or
will it be a waste of time. Some of us is only users with no programming
skills, but maybe we can contribute by accumulating info like this for
the programmers.
Just a thought 
Use it
Don't use it
