Jesse and Seva,
thank you for pointing out this problem. It was a simple typo (actually
failure to substitute some old code for new) that resulted in this
deficiency. Of course this should work. Latest SVN fixes this bug.
BTW - note that the classes alpha,beta etc are somewhat redundant in
your example, since the real selection is made by $sys.uqhost
