Yeah, I've implemented this sort of thing for market data projects  
(not sure where it is at the moment unfortunately).  It would  
probably be useful to distribute such a thing with quickfix.

If you don't care about overhead (either memory or disk writes), then  
you can use either of those stores if you use the ResetOnDisconnect  
and ResetOnLogout settings.  These will make sure your sequence  
numbers get reset to 1 no matter what store you use.  If you are  
worried about the overhead, then what should work would be to  
implement some sort of NullStore which implements the sequence/ 
creation time methods like the memory store.  Then just make the set 
() method do nothing, and have the get() method always return an  
empty vector.  Then using those two configuration settings you should  
get the effect you are looking for.
