Our implementation actually support this on the command line:

  snmpwalk -u schoenw ssh:schoenw at host.example.com:1234 ifTable

[I would prefer to get rid of the '-u schoenw' part but NET-SNMP
 5.3.0.1 seems to insist on having the -u option for v3; I guess we
 have to dig deeper.]

We currently don't implement any MIB objects but it seems straight
forward and operationally useful to support the 'user@' part. So I am
kind of in favour of this proposal.
