The current meteor router needs to be updated to use Blaze.

In some cases Meteor router is preferable to Iron-router for smaller simpler projects.

Do you want to send me a PR? (or even take over the project?)

It probably won't be too tricky but I'm not using this guy on any projects any more so I can't test it properly really..
