A few things apply, depending on how you fetch the drafts and what you
want to do.
- From some other machine, sync them into Dropbox and read and edit
them straight from Dropbox on the iPad using Plaintext (set its
directory to "/" which gives you all of the Dropbox directory,
otherwise it just looks in /plaintext)
- Instapaper - have a bookmark in your browser so you can save drafts
from the web to instapaper for offline reading.
- TexTastic is a syntax aware editor that even knows about XML and
DTDs and has a line of keys "commonly used in programming".
