Just FYI, I'm actively working on this re-work, and it's mostly 
finished.  I'm just running some benchmarks on this change and see what 
changes we should be expecting performance-wise.  I'll write something 
up and summarize my findings soon.

And just to get this out there, I am the primary maintainer of MDDS (for 
good or bad).  So, in case you have any questions, feel free to contact 
me.

Both Dennis and Lubos should also be fairly familiar with MDDS based on 
their past contribution history.

Best,

Kohei
