Jason just chose the wrong example, but he is correct.  Basically, we ship 
anything we're forced to, if there's some reason we can't rely on the 
distro.  Perl-tk, for example.  As we become more distro independent, I 
fear the circumstance will only become more prevalent.  SSH is off the 
shiplist because it can work at the moment...  but it is entirely possible 
to reach a point where a given ssh configuration (OSCAR does the 
configuration) can't be the same between two distros or versions.  That's 
just the nature of the package.  The same configuration file and/or path is 
far from guaranteed to work between distros and versions.  So in the event 
of a conflict, we're going to be faced with two options:
1)  Begin to create a matrix of ssh configurations that we test with their 
respective versions/distros.
2)  Ship ssh again and not have to worry about it.

We're essentially just cruising right now, because our OS support is narrow 
and it just works.  I hope we continue to cruise for a long time, and we'll 
cross this bridge when/if we get to it.

Option 1 is possible to do of course, but this circumstance could happen 
with other critical components too and Option 1 doesn't scale as well 
laborwise... and the more distro independent we get the more likely it is 
to occur.
