Everyone involved in the project maybe, but not everyone interested in "a 
block device for HA clusters".  And you don't want to turn them of by using 
terminology to explain terminology, especially when it's misleading.  Many 
OpenSource projects fail merely for this reason.

Ok, so maybe change the description to reflect this capability.
Something like:  DRBD is an independent, synch/async replicated block device.
