Brian ,It looks interesting but you should be confident enough altering a FS source code :) , that I wont bother at least. And I guess, you have to recompile FS each time you are making a change in that string?

A code snippet :
 if (user_agent_filter) {
                if (switch_regex_match(user_agent, user_agent_filter) == SWITCH_STATUS_SUCCESS) {
                        if (sofia_test_pflag(profile, PFLAG_LOG_AUTH_FAIL)) {
                                switch_log_printf(SWITCH_CHANNEL_LOG, SWITCH_LOG_DEBUG,
                                                                  "SIP auth OK (REGISTER) due to user-agent-filter.  Filter \"%s\" User-Agent \"%s\"\n", user_agent_filter, user_agent);
                        }
                } else {
                        ret = AUTH_FORBIDDEN;
                        if (sofia_test_pflag(profile, PFLAG_LOG_AUTH_FAIL)) {
                                switch_log_printf(SWITCH_CHANNEL_LOG, SWITCH_LOG_WARNING,
                                                                  "SIP auth failure (REGISTER) due to user-agent-filter.  Filter \"%s\" User-Agent \"%s\"\n", user_agent_filter,
                                                                  user_agent);
                        }
                        goto end;
                }
        }

 can block a specific User-agent comparing that value in the first nested IF condition.
But my vote goes to xml_curl method !

You guys try way too hard.

sofia_reg.c:                    if (!strcasecmp(var, "user-agent-filter")) {

This is a sofia profile param that you can put a regex in and filter it out.  ;)
