Absolutely. We have 5 subnets and 4 HNs, and the combination of HNs and 
IPs is entirely arbitrary. Huzzah for proxy arp, eh?

I do have some odd issues now and then, which I suspect make this not a 
great idea even though it does work.

One: I have to send out gratuitous ARP (I wrote a garpd if you want it) 
or else HNs tend to forget who has which IPs.

Two: Traffic between subnets and between HNs still seems to transit the 
router; this means double-transiting our cable to the router.

So I don't know that using mixed subnets is necessarily a great idea for 
production use. If anybody has advice on the matter, my eyes are wide 
open too!
