I hate to pick at details, but does this mean to not set up digipeaters 
on HF, or to not request a digipeat in your transmitted path?  It would 
seem more like the latter because otherwise there'd be no digipeaters 
around even if you wanted to use one for some reason.

And the logical follow-on, based on the response I read from the 
European station, is what alias is supposed to be used if a digipeater 
is configured, but hopefully only used in extreme duress?  I've seen 
ECHO documented on HF APRS most often, but I also see that APRS 
Messenger is doing some WIDE* stuff and the mention was made for WIDE2 
or some-such earlier today.
