Python-cgi Web Cobrowsing app

[mlorfeld]

I posted this message earlier, but as it was on Christmas Eve, so
apologies for those who have read, but still an urgent request for
your thoughts.

I am involved with a project that is developing a web based
collaboration tool.  Currently we are using web-embedded voice over IP
for classroom and other purposes (http://www.cu-hearme.com).  To
better communicate we would like to enable everyone involved to be
able to Cobrowse.  By cobrowse I mean when one person enters a url (in
a frame for instance) everyone in that collaboration session would be
pushed the same web page.  I have looked at java implementations
(coldbeans java servlets) as well as integrated collaborations tools
(www.blackboard.com).  These however don't quite fit the niche we are
looking for.  I have also looked at Zope, yet as I'm posting this, I
am still just browsing through the documentation so I don't know if it
is even the right way to look.  Another approach to this that I've
been tinkering with is using a python cgi script to call from an sql
database the most recent url posted.  I desprately need another
perspective, as I have a gut instinct I'm approaching this the wrong
way.  I believe that python would be the best developement language as
it lends itself nicely for rapid developement.  Any suggestions, code,
directions would be greatly appreciated.  Again the goal is to allow
for a member of a group to push a URL to others real time.  This needs
to be done either server side, or within the browser as
interoperability is essential.

Thanks,
