We could draw an arbitrary line to keep the number small. For example, 
there are (I think) about 540 existing IDs in the database, including all 
the links. If you draw that line at population 500,000, there are a little 
over 1000 cities that qualify, probably meaning (rough guess) the addition 
of 700-800 links - less than 80KB. I can't imagine that's an issue for any 
current embedded system, is it?

Here's a sampling of the (mostly-not-well-known) cities on the 500K "bubble":

Denpasar, Indonesia
Lipetsk, Russia
Dengta, China
Tuxtla Gutiérrez, Mexico
Songkhla, Thailand
Mariupol, Ukraine
Danjiangkou, China
Chiclayo, Peru
Penglai, China
Oaxaca de Juárez, Mexico
Aba, Nigeria
Astrakhan, Russia
MACAO, China : Macao SAR
Eskisehir, Turkey
Shishi, China
Kannur, India
Ananindeua, Brazil
Bokaro Steel City, India
Kolhapur, India
Xinzhou, China
Joinville, Brazil
Dangyang, China
Londrina, Brazil

There might be cause to add some others below that line, like 
capital/commercial capital status, top "n" within a country (depending on 
area maybe), etc. It could also be completely or partially optional (e.g. 
500k+, 100-500k, 50-100k pop files), allowing the specific implementation 
to choose to include as much or as little as they have room for. Include 
specific support for a "local" file that can override the stock database, 
and the implementation and user can do whatever they want.
