vDS port limits

Mnaging the maximum number of ports you can have on a distributed switch has always been difficult for those of us running large clouds.  It appears that with vSphere 5.1 that limit has mostly been removed.  In vSphere 4.0 the limit was 4,096, in 4.1, it was 8,192 but could be modified with PowerCLI to 20,000.  As of vSphere 5.0 the limit was 30k, now in 5.1 that limit is 60k.  However today we discovered the limit in the database is actually 2,147,483,647 (2.1Billion).  I guess I won't have to worry about those errors anymore...
