Well, perhaps a clue. When I run luaotfload-tool help, it shows me

The font database will be saved to:
c:/users/egc/AppData/Local/MikTeX/2.9/luatex-cache/generic/names/luaotfload-names.lua
c:/users/egc/AppData/Local/MikTeX/2.9/luatex-cache/generic/names/luaotfload-names.luc

and then...nothing else. I get no statement about where the font cache 
will be written to (i.e., I don't see anything like

The font cache will be written to
        /home/phg/src/texlive2013/texmf-var/luatex-cache/generic/fonts



In fact other than the statements about where the font database will be 
written to, runing luaotfload-tool --help shows me nothing else. At all.

This might be the clue. If I delete luatex-cache from 
c:/users/egc/AppData/Local/MikTeX/2.9/ (i.e., start over), bring up a 
command shell, and then run

luaotfload-tool --update --force

It creates luatex-cache, then generic, and then names but...then quits 
with the following error message:

luatofload | db: scanning TEXMF and OS fonts...
luaotfload -tool: Windows API error 5: Access is denied.
luaotfload-tool: Data: C:/users/egc/Templates

and then it exits.

Now, whats odd is that I get the above if I run luaotfload-tool. But, if 
instead, I (i) delete the luatex-cache file (again, start over), and 
then try to compile a MWE that uses fontspec, it grinds along, then

luaotfload | db : Font name database not found, generating a new one.
luaotfload | db: This can take several minutes; please be patient.

and, as before, \fonts and \names get created, \fonts contains the 
fonts, but \names is empty.

So, even though I 'shouldn't', I bring up a cmd window, and as admin, 
run luaotfload-tool --update --force. Runs to completion. Fonts in 
\fonts, and (importantly) in \names, see luaotfload-names.lua and 
luaotfload-names.luc

Now, try to compile MWE, and once again, I get all those ... could not 
write to cache messages. Document compiles, but still...
