The xend toolstack supports arbitrary external block device types.  We
have block-iscsi and block-npiv,  and the drbd project provides
block-drbd.  I'm quite sure I've seen other custom block types as well. 
Will these arbitrary block device types still be supported in the new
toolstack?

Thanks,
Jim
