There's no reason the plugin couldn't be e.g. 
appdir/lib/Dancer/Plugin/MyPlugin.pm, if that's what you're asking.

There's no absolute need for plugins to live under the Dancer::Plugin 
namespace, although it's probably a good idea - and also, the plugin_setting() 
method exposed by Dancer::Plugin to allow plugins to get their config might 
not work properly as I think it expects to remove Dancer::Plugin:: from the 
start of the package name.

If you really want your plugin under a different namespace - try it and see :)

If you 'use Dancer' as well as 'use Dancer::Plugin' within your plugin, I 
think you should be able to call template() from within the plugin.
