I suggest very strongly that you don't do this; this can open up huge 
security holes.  Say 'server.iniLabel' is equal to 'import os; 
os.system('rm -rf /'); foo': Danger Can Happen!

Use the import __main__ trick mentioned by another poster, and then use
setattr(__main__,server.iniLabel,server) to inject the values into the
__main__ namespace.  But beware!  This could cause bugs, too (if
server.iniLabel is the same as the name of a builtin or one of your
functions).  A dictionary (as you are considering) is the safest way to
go.
