The change to using a string to specify the backend happened just a few
weeks ago, before that it was using an enum named... you guessed it:
wxWebViewBackend. The enum values were

>>> for d in dir(wx.html2):
... if 'backend' in d.lower():
... print d
...
WEB_VIEW_BACKEND_DEFAULT
WEB_VIEW_BACKEND_IE
WEB_VIEW_BACKEND_WEBKIT
>>>

However the only backend available for Windows is the IE backend. The
architecture is designed to allow others, but none have been written and
added to wxWidgets yet. I think I read something about a webkit plugin
for Windows being worked on, but so far it hasn't been incorporated into
wxWidgets.

The change to using a string to specify the backend happened just a few
weeks ago, before that it was using an enum named... you guessed it:
wxWebViewBackend.  The enum values were

  WEB_VIEW_BACKEND_DEFAULT
  WEB_VIEW_BACKEND_IE
  WEB_VIEW_BACKEND_WEBKIT

So I was too optimistic :)
I'll either wait or try wxwebconnect then...
Thank you

CEF (Embedded Chrome )could be a nice option:

There are Python bindings already, though not sure they'd help here:

http://code.google.com/p/cefpython/

oh -- they might, they have a sample of embedding CEF in wxPython!
