Its not dangerous'; its just not *shown* to be safe. But then, what is?  

Don't make NetBSD yell that its outright dangerous, because it it
isn't necessarily dangerous; and sometimes network cards really are the 
best source of entropy available.

Emit a syslog message worning that network traffic may be subject
entropy-damaging attacks, or something like that?
