I can't beat that :-) but FYI there are two SPs in InCommon metadata
with at least 100 ACS endpoints:

$ MD_LOCATION=http://md.incommon.org/InCommon/InCommon-metadata.xml
$ curl --silent $MD_LOCATION | grep -F 'index="100"' | wc -l
       2

I don't know if either of them signs AuthnRequests, however.
