There's a new plugin that Michael Herger is hosting called TimeSpeller, which is a Date and Time screensaver that prints the time in words, e.g. "quarter to ten". The English translation of this is British English ("midday" rather than "noon"). It would be nice to have regional subtypes for such plugins. 

I'm thinking something like using hyphenated names for regional subtypes -- "EN-US" for "English (US)", "EN-UK" for "English (Britain)", "ES-MX" for "Español (Mexico)", etc.

If a user chose a subtype like ES-MX, Slimserver would look first for "ES-MX" strings, then "ES", and only then look at the failsafe language.

sample patches for 6.5.0:
