@patdavid I would highly recommend looking at todo.txt. It's a protocol for saving GTD or similar project and time management todo lists in plain text files.
On my phone I use simpletask as a front end for my todo.txt file. On my computer I use my own program to manipulate the todo.txt file. Using plain text files means u can write scripts quickly to grep or >> the file.
I wrote a blog post on this recently if you're interested?
