Does the clustering code have any platform specific handling ? For instance,
does an Alpha treat a VAX any differently than another Alpha ?

Or is the clustering code and protocol totally agnostic to a point where if an
 PowerPC or Z80 version of VMS became available tomorrow, I could include in
in a VAX or Alpha cluster with those machines simply accepting the platform
name as a string that doesn't get used in conditional execution ?

In other words, for an Alpha to support a new platform in a cluster, must the
Alpha have any code specific to that platform ?

*IF* VAX doesn't cluster well with IA64, would it be more likely because the
VAX is missing something to interface to IA64, or because IA64 forgot to
include an IF statement to deal with VAX architecture ?
