Not sure what you are looking for, but it seems to me, that your current static site is just delivered from server to browser. So no scripting or background processing. That would make it a little more complicate to get values from meteor for you.
You may add DDP to your static client and script connection etc. but why not do it the easy way.
Just deliver your static web site from meteor. You will just create one template around your current page. Then you can use for example all the blaze options to access all meteor vars.
I want to deliver a number from the meteor application, to the static (SimpleHTTPServer) site.
I am aware you can use a meteor call to get the value to a client page, and jQuery to change the value on the static site, but how do I get the number from the application to the static site.
