Yes, I'm using the mod_pubsub Perl module under modperl.

No, there are no single byte keepalives.  The keepalives I've seen with
my 1.3 installation are http continuations consisting of 8 bytes
containing spaces and CRLFS, which are sent once per second or more.
The mod_pubsub.org based apps contain at least 127 bytes of javascript
(many are far more wasteful), but only send every 15 to 30 seconds.

The documention for the project doesn't get into anything at this depth,
as far as I've seen.
