How does SQIUN differ to a typical HTTP SPARQL endpoint? So far it accepts a
"query" parameter as a SPARQL select statement and executes the parameter on
(some configured?) SPARQL endpoints from looking at the single sourcefile I
could find [1]. Having said that, I have been holding off getting my bio2rdf
server to actually process rdf but it doesn't look so hard now. (The bio2rdf
server is actually more generic than just biology or even bio2rdf but it is
still named that in response to its origins. And in contrast to SQUIN it
focuses on CONSTRUCT queries rather than SELECT)

On the subject of mashups I have been thinking in the last few days of
combining the bio2rdf server with the pipes.deri.org interface for mashups,
as some fairly sophisticated mashups can be done on pipes.deri.org, but a
lot of the generic queries seem to be better handled at the client level
where people can control with configurations what endpoints are used and
have backups if a particular endpoint fails.
