Using nearlyfreespeech.net would not work for you anyway; although they support plenty of programming languages, they only support them as CGI scripts invoked by Apache, not as long-running processes which do the work of serving pages themselves, which is how the arc webserver works.
The only real options for hosting an arc webserver, as far as I can tall, are: host it yourself, colo it, or use a VPS.
Thanks for responding. It looks like the best choice for me is to host it on my desktop for now, hoping my internet connection doesn't suck enough to prevent it working.
