Safari clues and Flash pubsub

Hey all,

I actually got around to tinkering with the new tarball last night. I'm 
happy to report that python_pubsub seems to run just fine on the Python 
2.2 install that comes with Mac OS X 10.2.

I spent some time trying to track down the source of the Safari glitch 
we've been seeing. It looks like the onTunnelStatus callback in 
pubsub.js is not being called, as we suspected. The tunnel frame passes 
the isReady check and the connector has a valid handle to it, so it's 
not a frame access problem AFAICT.

I also messed around with hooking into python_pubsub from ActionScript 
(Flash). I don't know if Jos is still on this list (Hello, Jos? Do you 
still have your Flash connector code lying around somewhere?), but I was 
able to confirm his finding that the Flash XMLSocket object works fine 
as a tunnel manager, and the new "flash" wire format works great.

The remaining problem is that XMLSocket still only gets us ports 1024 
and above. I tried using the new wire format on the other Flash objects 
that support HTTP on :80 (like the XML and LoadVars objects), and while 
the new format allows their onLoad handlers to be invoked (a step 
forward), there's still no way to access the data returned from the 
server. The XMLSocket is specifically designed for persistent 
connections and looks for the null byte to fire its handlers; I fear 
that these other objects may be listening for an actual Connection:close 
before making any response data available.

That said, it looks like we could easily create a pubsub_actionscript 
library right now, just restricted to ports 1024 and up. That wouldn't 
be entirely bad.
