Not necessarily a bad idea if we want to start from scratch.  However,
using unreliable datagrams (UD) means ignoring most of the performance
features of IB, since you're limited to single packet messages and
have to take care of all the reliable delivery in software.  You'd
probably be lucky to get 1/3 the performance you can get by using
reliable connected transport.
