Some value that is assigned to each entity that can create a new record. That entity then appends the value to the PK to stamp it as globally unique. As long as each "node" has a unique node value, none of the PKs should be duplicate.

Alternatively,

lcGuid = SPACE(16)
DECLARE INTEGER CoCreateGuid IN "Ole32.dll" STRING @
=CoCreateGuid(@lcGuid)
lcNewPK = lcGuid

Creates a globally unique 128 bit identifier using the same algorithm used by all other windows computers. This value is virtually guaranteed to be unique across space and time. IOW, noone, nowhere, on any machine will ever create the same value.
