No, that's very old-fashioned thinking. A gazillion little one-off 
solutions that don't interoperate unless you pay an expert to be "_very_ 
careful and know[] _exactly_ what [they] are doing" (???) Come on, give 
me a break. One main benefit of standards is to ensure that even people 
who don't completely know what they are doing and/or don't have enough 
money to pay high-priced experts to hand-hold their systems, can get 
products from different vendors and codebases to interoperate with each 
other. This is a *good* thing, unless you happen to be one of those 
high-priced experts gouging their customers for "private" solutions 
instead of standards-based ones...

The standards dictate that the serial number is incremented when the 
zone contents change. How hard is that to get right? Why would you 
defend such total incompetence on the part of Microsoft? (Actually, I'm 
being generous to Microsoft here; some would accuse them of deliberate 
sabotage). As long as the serial number is handled properly, and zone 
transfers work, then all of these other "private" replication schemes 
interoperate with the standards-based one.
