True, we will only use ARP & UDP and we could probably do without ARP if 
we really have to. Backup solution if memory protection is deemed to be 
insufficient will be to roll our own UDP parser. Should not be too 
difficult but I'm still guessing that we'll have to invest a 
considerable amount of time to get it as stable and well tested as those 
parts of lwIP are now.

Thanks again for insightful comments.
