Lodestone API exposure

Hi!
I have a small service on http://simbiat.ru/FFTracker allowing to track FC progress: who joined, ranks changes; track each member's leveling progress. If main page loads long (there are lots of companies registered): http://simbiat.ru/fftracker/company/...1035923213559/ as example of a FC page with all features in it.
Some in-game friends asked me if I can do something similar with Linkshells to track inactive members. I can, but without tracking of inactivity, since last login time is shown only on your wall for people you are following. That's why inactivity tracking on FC pages is also determined by specific rank assignment, not actual inactivity.
My question is: can SE expose last login time for all characters in Lodestone?
Or better yet: expose the Lodestone API, so that I could request info from Lodestone for my service without parsing HTML (with older XIVSync code)? Or even better: maybe SE can consider making something similar in Lodestone itself? I'd be happy to assist.

I had a feeling that this thread would be buried under GM feedbacks... Personally I think one thread for GM could be enough (=

bump, in hopes someone will actually read it
