In some use cases, it is useful to fetch the YASQE configuration from an external URL. This allows you to e.g. fetch the shown YASQE query from an externally hosted page. This might be interesting when you've published your SPARQL queries in separate files as part of your documentation, and you would like to use YASQE as a means of accessing it. This example gist does exactly that: when a 'queryRef' URL parameter is passed, it fetches the YASQE query with an asynchronous call from the URL.

Thanks a lot! With the kind help of Laurens, I've created a public hub for executing queries on GitHub at http://zbw.eu/beta/sparql-gui. It can be used (without any warranty) to execute arbitrary queries saved on GitHub via a query like this:
http://zbw.eu/beta/sparql-gui/?endpoint=http://zbw.eu/beta/sparql/stwv/query&queryRef=https://api.github.com/repos/jneubert/skos-history/contents/sparql/count_added_concepts.rq
to execute the query at https://github.com/jneubert/skos-history/blob/master/sparql/count_added_concepts.rq on the endpoint given in the URL. (For more stuff like this, see expample queries for the skos-history projekt.)
