I've had success syncing my SublimeText config across machines using homesick (https://github.com/technicalpickles/homesick), but this looks pretty slick.

One issue with syncing configs using either method right now is that certain keyboard shortcuts don't make sense across OS types, and your font size may not work well at different monitor resolutions (especially retina vs non-retina). See http://www.sublimetext.com/forum/viewtopic.php?f=2&t=5135 for related discussion. If you could incorporate per-OS/machine config overrides into this it would be very handy.

you can define the settings in os-specific settings files in ST already
