[JDEV] Looking for transport development guidance

[Peter Saint-Andre]

Hi Mark, 

I have a preliminary doc available on the MIO API for 1.4 transport
development. It will probably get moved to jabber.org at some point
and/or incorporated into a more complete document, but right now it is
parked on my site at:

http://www.saint-andre.com/jabber/docs/mio.html

Hope this helps.
