Nick,

I know you said 'serverless clients' but you have to be serving the js from
somewhere right?

If you are using nginx it can be as simple as:

location /nova/ {
   proxy_pass: http://nova-api.trystack.org;
}

then you can POST to yourserver/nova/v.02/.  from the browser

etc.
(it's just about as simple on apache but you'd have to look it up)


But then i guess this won't work for you if you are writing
some distributable component/plugin/library.

(sorry if you've already dismissed this option but i thought it worth a
shot since it has worked flawlessly for me in the past)
