Greg,
I would say that an event-based approach is both a worthwhile
aspiration, and increasingly a working reality. The Europeana
Connection Kit (ECK) provides a standard LIDO mapping as being "the most
popular exchange format for museums" [1]. Major CMS vendors are
announcing support for the ECK - last month it was the turn of Adlib -
so I expect the pressure will be on the remainder to offer this
functionality in their own offerings.
The extent to which offering support for LIDO reflects a truly
event-based model in the underlying system is something you would have
to ask individual vendors about.
Whatever conclusions you draw about LIDO would apply equally, of course,
to the CIDOC CRM, which is also event-based. My own view is that you
can say very little of value about cultural heritage, using simplistic
dbpedia-style binary links between objects and "other stuff".
Best wishes,
Richard

I can see the benefits of LIDO, like the potential to capture related information about what has happened to an object over time and the flexibility it affords in the search and display of this data, but I wonder if it is a beautiful theory rather than a workable solution. My very frank question: is LIDO really advantageous and do institutions plan on utilizing event relationships in their discovery systems?

Other events, like printing and distributing a print, are handled in a note or edition display statement, leaving the structured event properties unused. This suggests that data is being mapped to LIDO from an object-based CMS.

Still, it seems that if one intends to deliver data structured in the event conceptual model, at even a medium level of specificity, one must collect the data in a schema that allows mapping into this model. In other words, it will be much easier to export rich LIDO metadata from a CMS that captures the relationships of event information.

I'm wondering if data input tools have changed to accommodate LIDO's event based approach - do they allow multiple events complete with creator, date, location, materials, etc.? Do most systems still use the conceptual model, "here are all the dates, here are all the locations, here are all the materials" or are they changing to, "an event happened to this object on this date, at this location and these materials were used, another event happened to this object on this date..."? I made a mockup of a simple event-based input form<https://docs.google.com/drawings/d/1ywI_B6-rTIxvt0vo63ienkYHu3sbvmdXpcncpkWEnFo/edit?usp=sharing>, just to see how it might look.
