"username="" looks like it is supported by smbfs's mount helper, 
although not the way you would expect, it seems to try your username and 
then try a null user name (empty string)

The following code in mount.cifs.c rejects a null username though - we 
will need to fix that.   If you want to track this, you can open a 
bugzilla bug at bugzilla.samba.org and you will get notified when we fix 
it - but it looks easy.

                } else if (strncmp(data, "user", 4) == 0) {

                        if (!value || !*value) {
                                if(data[4] == '\0') {
                                        if(verboseflag)
                                                printf("\nskipping empty 
user mount parameter\n");
                                        /* remove the parm since it 
would otherwise be confusing
                                        to the kernel code which would 
think it was a real username */
                                        goto nocopy;
                                } else {
                                        printf("username specified with 
no parameter\n");
                                        return 1;       /* needs_arg; */
                                }
                        } else {
                                if (strnlen(value, 260) < 260) {
                                        got_user=1;
