Port 15000 is used as a default for Borland/Visibroker's Gatekeeper product.  It allows CORBA applications to multiplex 
through a single firewall port.  

Since your curious visitor used port 15000 as a source and a destination, it looks as though they might have been 
trying to bypass restrictions by using a port that might be let through.  80 would be a better choice, though.  Who 
runs Gatekeeper, anyway? <g>

On your question about hosts scanned:  Can you see any relation between the numbers scanned and your actual network?  
i.e. did they have some pre-knowledge of what to poke for?
