Great!

Is it possible to remap Esc to other keys? Most vim users use jj or jk instead of Esc and when in command mode space instead of :.

Vintage Mode is implemented entirely via key bindings and a few plugins (which come as commented python source). Everything is customisable, there are some details at http://www.sublimetext.com/docs/2/vintage.html

I couldn't help but send you money Sir. Please keep up the great work!

Think this build adds in ^-[ as an alias for Esc.
