Generating unique ids in Mnesia

[Joel Reymont]

Folks,

I need to maintain a table of players in Mnesia and I would like to  
assign players a unique id when they are added. Right now I generate  
a tuple of {timestamp hash, pid hash} and then hash that once more to  
get a unique id.

Is there an easier way to do this in Mnesia? The ids can be  
sequential or random, they just can't repeat themselves as the table  
is a set. I guess I'm looking for something like a max aggregator on  
a Mnesia column.

     Thanks, Joel
