I'm running sFlow on EX4200 VCs with JUNOS 9.6R3 and everything works
as expected.  The only difference from your configuration is that I'm
exporting to a collecter via an RVI.

Point of annoyance - JUNOS fails to expand apply-group interface
wildcards under [edit protocols sflow].  So I'm going to need a few
hundreds lines of config on my VCs instead of a nice and compact
group.  I don't suppose anyone has discovered a way around this?
