Is it possible to embed passwords in a filename?

[Kirk Strauser]

I routinely access a few machines with horridly difficult-to-type
machine-generated passwords.  Arguments to the security implications aside,
is it or could it be possible to embed passwords in a Tramp filename?  For
example:

  
/multi:ssh:address@hidden:ssh:address@hidden:su:address@hidden"address@hidden@2V@&It":/foo

This would be tremendously helpful if it is indeed possible.
