I don't think so: vsyslog() in libc (as can be seen in the OpenSolaris
sources: usr/src/lib/libc/port/gen/syslog.c) uses putmsg to communicate
with syslogd.

Fails: in truss, one sees

10807/4:        so_socket(PF_UNIX, SOCK_STREAM, 0, "", SOV_DEFAULT) = 3
10807/4:        fcntl(3, F_SETFD, 0x00000001)                   = 0
10807/4:        setsockopt(3, SOL_SOCKET, SO_REUSEADDR, 0xFE48F4A0, 4,
SOV_DEFAULT) = 0
10807/4:        setsockopt(3, SOL_SOCKET, SO_BROADCAST, 0xFE48F4A8, 4,
SOV_DEFAULT) = 0
10807/4:        connect(3, 0xFE4B5588, 15, SOV_DEFAULT)         Err#95 ENOTSOCK
10807/4:                AF_UNIX  name = /dev/conslog

This isn't a unix domain socket and cannot be used as such.
