I managed to customize it per template, using your hacks with a slight change on the plugin changes:

Still find

$vbulletin->templatecache['FORUMHOME'] = str_replace($Position, $Position . ' $Shoutbox', $vbulletin->templatecache['FORUMHOME']);

Then instead of replacing FORUMHOME by navbar, keep it like it is and insert above it

$Position = '<!-- put vBShout here -->';

No go on FORUMHOME and put <!-- put vBShout here --> where you want the shoutbox to be at forum home
For example
<td><!-- put vBShout here --></td>

Then on each template that you want a shoutbox put $Shoutbox where it should be
example

<td>$Shoutbox</td>

I wanted Shoutbox on the bottom for FORUMHOME, FORUMDISPLAY and thread viewing and on top for all RPG Inferno screens.
Worked like a charm!

PS: Is it just me or the RED color makes the text green here at vbulletin.org ?
