Hi,
I made a clone of pypi.python.org/pypi/PdbSublimeTextSupport
This lets you see the current line being debugged in an active Python debugger (PDB) session live in Sublime Text as you step through.
It is a bit fiddly to install, but seems to work. Code here: github.com/optilude/PdbSublimeTextSupport
Cheers,
Martin
