Tom, I'm copying metadata-support since this may be of general interest:

Correct. As an SP owner, you would have to explicitly opt in to be
exported to eduGAIN.

Yes, that's what I would expect. There are no issues with the
Shibboleth SP software AFAIK.

Yes, Tom, that's right. If you're not yet ready to export your SP
metadata to eduGAIN, it's best to filter global IdPs from your
metadata feed. Why? Because if (on the off-chance) an international
user were to select their IdP on your discovery interface, they would
immediately experience an error at the IdP since that IdP does not
have access to your metadata. So the simplest thing to do is filter
global IdPs from your discovery interface. Instructions for doing so
are documented in the wiki. [1]

At the bottom of that page is a complete configuration for SPs such as
yours. The config on that page exposes all IdPs with the
registered-by-incommon entity attribute except for those IdPs with the
hide-from-discovery entity attribute. I'm pretty sure that's what you
want to do.

Well, the best overall reference we have is the Getting Ready for
eduGAIN [2] wiki page. If you have any questions about any of that,
please let me know.

Cheers! :-)
