Log File Parsing

This question comes from curiosity. I know parts of this have recently have been classified as against the ToS, at least portions of it.

However I have thought of a cool idea, logs can be used of course to see where people can do better, and that application of it I do not think is bad, its the automated predictions or macro generation that is the problem.

So my idea was to make an application that forwards log data to a database, that can then do a "turn for turn" replay of the battle. I of course plan to be the one to play around and see if I can make it work, just want to see if that is against ToS. I would not be building it to share, just give our FC a little something extra to help us get through content (we are very slow). Plus I love a challenge.

So is this allowed? If so is there anything I can read to better understand the log files? I know third party applications will eventually be allowed in the UI and I would be interested in doing things for it. This can give me something to do until then.
