	Thanks for the feedback. That was our sense as well, but
	I know that (in the past, anyway) some folks had built
	tools that used 'sh ip bgp' format input data. We didn't
	want to break those. As I mentioned to Randy, we're
	thinking we can generate 'sh ip bgp' format from MRT data
	(but there is still the "peer partity" issue; we're
	working that now). 

	One other note on all of this. Part of the reason we
	wanted to take down the screen scraping to get the 'sh ip
	bgp' stuff is that is under
	quite a bit of CPU and memory stress. While we're in the
	process of trying to upgrade that box, resources are
	tight and it would be useful if we could free up the
	resources used in collecting that data.
