Thanks Adam. A follow up observation (enhancement request really): I
like the way the filter code gets the document so it can use the
req.query to only push certain notification to certain clients.
Unfortunately when a document gets deleted all I get is something like
this:

{"seq":389,"id":"8f8bb53dbf8eb9be81923fea21072386","changes":[{"rev":"2-30b513fc78ad7eadd4db4b7f87591338"}],"deleted":true}

It would be nice to have the actual doc be part of this so that the
filter can be more intelligent in its routing decision. For example,
only notify certain interested clients about the deletion.

Thanks,

K.
