+## Real-time capabilities
+
+Different real-time guarantees are required for different use cases. Low
+frequency sensing needs only soft real-time support and can handle less timing
+accuracy so long as the timers support long timescales. High-frequency sensing
+and control applications need hard real-time guarantees and sub-millisecond
+timing accuracy.
+
+RIOT should deliver soft real-time performance by default, to cover the widest
+range of use cases. Programs with hard deadlines should be achievable with more
+expertise. It should provide timers which can competently handle the timescales
+of any application.

I was informed by @haukepetersen IIRC that the tickless scheduler allows people to satisfy hard deadlines if they know what they're doing. Perhaps he can disambiguate?
