Not if your contract requires five-nines reliablility and no more
than 180 minutes of downtime _ever_.  Is five-nines realistic?  For
most purposes, probably not, according to recent pronouncements (see,
e.g. <http://www.bcr.com/bcrmag/2002/05/p22.asp>).  But it's in
lots of contracts anyway.

The more or less standard way of doing this is to stream the
PITR-required stuff to another device on another controller -- lots
of people stream to tape.  People have been doing this for ages,
partly because disks used to be (a) expensive and (b) unreliable.
