Different cost centers...
Don't you love it when stuff gets lodged into creative cost centers?
I usually leave it for accounting/sales/service to figure out how to bill when "Can you train staff on use of X&Y?" turns out to be "Oh, while you're here, we also need a new revision of E, feature upgrade to Z, rewire of M,P,R, and U...".
On a funny end note, better hope Stephen used 64 bit time notation, so when the tape drive the universe backup is on gets read-in after the Gnab Gib we have proper synchronization with the multiverse hypervisor.
Pint to start festivities early.
