Doesn't have to be platform-specific. Proofreading can even be done online. Plain text (.txt) is also platform-independent. Just make sure everyone is using the same file encoding or you will end up in a horrendous mess.
Since its a magazine we need a package which can scan the documents into an editable form while leaving the images intact and in the same page location as the original. Plain text files won't do.

Filipino readers who are accustomed to Roman script but don't know English, so they will be matching character-for-character without the brain silently correcting typos and/or scannos.
That's a poor assumption. The proof-reading is being handled by some local USA based college students.
