This is a great idea from a security perspective.
Currently, if a plugin author chooses to self-host his plugin and not
list it in the directory, a malicious individual could e-mail Matt and
ask for an entry in the plugin directory with the same slug. Then, the
malicious individual could release an 'update' to the plugin that could
0wn the blog.
However, having a GUID in place means users won't automagically get
updates to their plugins if a plugin author decides to have their plugin
hosted in the directory after a large quantity of users have already
downloaded a version that doesn't have a GUID.
I guess WordPress would have to still offer updates for plugins that
don't have a local GUID, but the slug matches. Or does that defeat the
purpose, or not make sense?
