For multihoming *clients*, you don't need HE (or, specifically, HE doesn't
solve the issue of *source* address failover anyway in it's current form).

Server multihoming works without HE if you can afford to be patient,
like, you're an SMTP client and it doesn't matter whether the TCP session
connects in 10ms or 2 minutes, as long as it transmits the mail in question
(which, incidentially, HE doesn't guarantee - it will give you "that 
address gave back SYN-ACK first" but no guarantees that the TCP path 
actually works for packets with data in)
