Add 32/64 bit information to python module fme

It would be very useful to get what version is being used to execute a pythoncaller when using for example the arcpy library. Is is therefore possible to add this information to the macroValues provided in the module fme?

example. fme.macroValues['FME_VERSION'] = 32bit

Example of situation in which it would be useful:

Perhaps as a system parameter too?
