You could also add it as a special case somewhere in KIO. E.g. make a 
KIO::DataSlave class that derives from KIO::Slave but that does all the 
handling itself instead of starting a seperate process.

It's a bit tricky to catch the actual "GET" request though since KIO::Job uses 
the Slave::connection() directly to send requests to the slave process.

Just making it its own seperate io-slave is probably by far the easiest.
