// embed a presumed allowed site (e.g. mozilla.org) in a frame, then
// change the location to the XPI and trigger the install. Or evil.com
// could do the same thing in a new window (more work to get around
// popup blocking, but possible).

// trust only the install URI. The former is unacceptably restrictive,
// the latter allows malicious sites to pester people with modal
// dialogs. As long as the trusted sites don't host bad content that's
// no worse than an endless stream of alert()s -- already possible.
// If the trusted sites don't even have an ftp server then even this
// level of annoyance is not possible.
//
// If a trusted site hosts an install with an exploitable flaw it
// might be possible that a malicious site would attempt to trick
