Afternoon,
I jumped on Backfish's app the hour it was released and quickly emailed them that it lacked ADFS support, and for any big companies supporting it (like me) was a deal breaker.
Got an almost immediate response and just be offered to become a beta tester for it, will let you know about how I find it soon.
PS what I would love is a sync application that can link to multiple companies, ie Dropbox, Google drive and so on.
