If you distribute preprocessed code, you need LAN speeds/latency for it to be faster than a local compilation. Otherwise, you need to have the exact same headers in addition to the exact same compiler installed everywhere. It MAY work otherwise, until it breaks in a subtle / obscure way one day and after tracking it down you will think maybe compilation doesn't take THAT long on a single machine :)

So all in all, I wouldn't say works outside of a well-controlled cluster on a LAN.
