    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?
