Would it be possible to make it volatile?

Could you please detail on that? I can see no obvious way in the manpage
(maybe I should use CVS version?) and I don't quite understand how it
would work. Is there some on-chip storage for linkkeys that gets read
by the windows drivers?

I'm asking, because I have the same problem when moving a bluetooth adapter 
between two different PCs. The headset will need to be re-paired with the 
other PC, whenever I do so (and I got to remove the linkkey before, of 
course).

I could try copying the link keys, as they are both linux (not sure, if 
that would work, but it sounds worth a try), but I doubt this is possible 
with windows.


CU, Andy
