I honestly don't know what cross ownership exists between mmz and esn. Only thing I would suggest is to check the top 20 list on both. I've been watching for a year but never pay much attention to top 20 lists (I'll likely never be on one unless I win lotto)
I don't think HC is the sole source of the recent rise. The catalyst was the iphone app approval ann which saw 100% rise in price (from .001) and a volume spike. Both of these did see esn get a fair bit of attention on the daytrading threads for example but prior to the ann and rise hc wasn't interested.
