This may be of use to anyone looking for a free site to host Karrigell apps.
VlexoFree recently installed Python 3.4. I have installed Karrigell 4 using the standard CGI installation instructions and it works. The only change I had to make was to copy the contents of the Karrigell version of .htaccess and add them to the top of the existing .htaccess file. I am not sure if WSGI support is available.
Search for VlexoFree if you are interested.
Cheers,
Jim
