A VPS owner would often set the reverse DNS to match their own domain, so I think reverse DNS data is not very useful for gauging the relative use of shared vs. VPS hosting.
But the VPS would all be on the same net block. Jamie has added that to his bot and it is finding those on EC2, Linode, Dreamhost, etc.
For example, here is an Amazon netblock: http://wikiapiary.com/wiki/Special:SearchByProperty/Has-20netblock-20organiz...
Compare with the Dreamhost netblock: http://wikiapiary.com/w/index.php?title=Special:SearchByProperty&offset=...
The question we are interested in is mainly whether a wiki is on a host with support for the installation of wiki-specific software. In general that is hard to figure out in an automated way, especially for less common providers / reverse DNS entries.
I will not dispute this ("hard to figure out"), but I will point out that the using the above information gives us a better idea than simply relying on reverse DNS.
