Please look at AIX's LVM and the way it does distribution of Physical Partitions vs. Linux LVM and its Pysical Extent "Striping".
In AIX they have something called the "Intra-Physical Volume Allocation Policy" that allows you to manage the distribution of Physical Partitions ("Extents" in Linux) between PVs.
Basically it simplifies the problem of adding a new PV if you want the data spread across as many PVs as possible.
I don't know enough to know if it could be incorporated if NetBSD uses the Linux LVM system (devmapper et al). But it would be a VAST improvement.
