I'd bet that 100 microseconds exceeds the resolution of the Android scheduler. If you actually need that much synchronization of action, I think you're out of luck. If you just need that small a skew between timestamp sources, I'm not sure.
I'm have no experience with IEEE-1588. However, www.ntp.org has a lot of information you'll find relevant background, including statistical studies of real-world experience with time synchronization, etc. But I don't think NTP will quite take you to the degree of synchronization you need; it does look to me like IEEE-1588 is the way to go.
