Otherwise, this discussion is about two different mechanisms to achieve the same end result.  My core argument is the the trie-based solution is much less complex overall, easier to implement and get right, and has numerous other benefits -- such as dead-simple rollbacks and the whole thing is parallelizable (different threads/CPUs/servers can maintain different sub-branches of a patricia tree, and report their results can easily be accumulated at the end -- this is not possible with BSTs).  If you want to contribute to this discussion, then please do.
