Yeah, they certainly can. That's effectively the way that I programmed
the MUD kernel that we used at work (not for games, but it's still
effectively a MUD), although I used async I/O facilities to abstract
away the actual select calls. It's as good as the multi-threaded model
(which is what I use in Minstrel Hall - every connection spawns a
thread, which does blocking reads and blocking writes; simplifies the
code when a command wants to delay the user, as it simply sleep()s),
and can often scale to more concurrent connections, although for the
bulk of servers that's not going to be an issue.
