hosting - is it possible to use google channel api without using rest of app engine -

for example if have remotely hosted site, can use google's new channel api? http://code.google.com/appengine/docs/python/channel/

if have site elsewhere, , want google create new channels, send data, etc, without being hosted on gae, or have hosted on gae?

if it's possible, please point me in right direction.

thanks.

a clever engineer write service in app engine exposes 2 channel api methods restful methods.

services not written in app engine wanted use service could, instead of calling channel api directly, proxy calls via rest above service.

clients receive messages use extant javascript library.

security, privacy, throttling, abuse detection, etc. left exercise reader.
