Hm, could have a look but I'm not 100% sure it'll work easily; Flash  
doesn't actually have a 'point' primitive, only lines. I guess drawing  
a very very short line might work, but I'll have to see how well it

Potlatch has its own API that talks in SWF and AMF (ActionScript  
Message Format) rather than XML.
