I noticed you plan to use both LS.
This could be great.
But I hope you have a work around for potential ID conflicts for accounts between the 2.
We had that issue when we made dev and takp share loginservers and dev was open signups.
Also don't think OSX will be able to login to yours through our loginserver with the current state of how that is handled because of the OSX client.
Otherwise, good going with this. Hope it plays out well
