Hi Peter,

Loading the geonames data into a local index is something I am
considering.  This is what I am doing with LCSH terms in EADitor.
Locally-created subjects and LCSH terms share the same Solr index.  I
just found the Atom feed for geonames.org, so I may opt the direction
of locally storing geonames data since updating the data is a
possibility.

The question is which of the attributes allowable to EAD <geogname>
can be used to capture the id of the geoname (e.g. '4250542' for
Springfield, Illinois)?  What about @source: "geonames:4250542"?

The source attribute is defined as "The source of the controlled
vocabulary term contained in the element. Available in subelements of
<controlaccess>, i.e., <corpname>, <famname>, <function>, <genreform>,
<geogname>, <name>, <occupation>, <persname>, <physdesc>, <subject>,
and <title>."

Geonames is the organization responsible for creating the term.  The
examples on the EAD site use "lcsh" for subject terms.  Is there any
reason that the id of the term itself, relative to geonames' service,
cannot be captured directly within the EAD source attribute?

Those databases can hold the appropriate linked data URIs like those for geonames, viaf, or eol, but, importantly, can also serve as a local authority for names *not* found in linked data sources. You could construct keys that conform to NMTOKEN, and the local infrastructure can look up the appropriate external URIs at delivery time. I'm taking this approach for TEI texts, where an @key attribute is available on many elements.
