Oh, thank you! That is exactly what I've been thinking. 
One reason that I think that The Fidelius charm is person or group 
specific, is That I think that The FC  is one of the protections that 
Dumbledore put on Privet Drive. Volde and any one who wished ill on 
Harry could look into the window of 4 Privet Drive and never see 
Harry. But the Weasley's found Harry, Mrs Weasley even sent a Muggle 
post  to 4PD. It was even connected to the Floo network. I think that 
the Fidelius charm allows ONLY the secret keeper to reveal the 
location of the person, any one else would probably hem and haw and 
change the subject.
