Android libraries performing facebook login, complications -

we developing android application , sdk(android-library) it. sdk integrated other partner applications. want utilize facebook our login provider across both app , sdk.

our understanding/plan partners need integrate app facebook(create app on developers.facebook.com , etc) , able utilize facebook sdk in our sdk, applicationid. send token on server access /me api facebook id utilize login id our system.

if we(via sdk) phone call fb session open , host application has authenticated fb, getting same token?

are there legal or other issues regarding this? privacy issue?

with facebook? with host application developers? is there way handle purely terms , conditions style stuff?

can somehow request fresh access token permissions need? solve issue?

we considering if able have seperate application id our sdk, wouldnt work because facebook requires associate keyhash application....

are there other instances these of libraries using facebook login? sounds should impossible somehow... otherwise advertisement libraries need integrate fb sdk access want.. came across this recent news article, sounds similar, not sure if is

edit: seems facebook ids application specific now.. bummer - http://code-worrier.com/blog/changes-in-facebook-graph-api-2-dot-0/
