Just a little nervous about messing this up.
Entirely gleaned from the posts on wmw.
This will in effect result in all your domains being hosted on the ip address (or block) - this will/could affect your rankings in some search engines (ie. google) if your sites are relying on links to from each other for there PR. Meaning - a link from a domain that is in the same IP block as your own is not as valuable as one completely unrelated.
I recommend posting a query in google asking if multiple sites on one IP will cause problems to get the SEO experts to look at this ;) DNS is such a turn off.
By the bye - most of my sites are on one IP - a virtual hosting package - so probably lots of others too. I haven't noticed any problems with links being ignored, sites not being indexed etc etc, even when the only link in existance is from my site ;)
