The best way to resolve conflicts is to not create them.  If you use the 
most significant bits of your int ID as a counter, and fill the least 
significant bits with conflict busting randomness, you'll be in good 
shape.  We (ZC) have a package that does just that which we really need 
to release.  If there's interest I'll take a stab at doing that soon.
