I have to say I disagree with this particular suggestion. Because there is no easy way to automate the process of making an OS list for each VPS plan and keeping it updated.

Dean has been spending substantial amount of his time for this community. We should not add him too much burdens requiring manual updates.

For the same reasons, the maintenance of the VPS Holders List should also be stopped.

As already said, OpenVZ available oses are almost already listed and they don't change at all. See my previous message.
Regarding KVM, the topic gets a bit complicated and I don't have much data to purpose a solution but as I have previously mentioned, there must be a OS list because if you don't pay for "Custom ISO Mount" service then you have to choose from a list given by provider.

If these lists are publicly available it is easy to create a scraper/crawler to automate and update the listing.

This post wasn't intended to create troubles and excessive work to @deanhills and the other staff. 

I don't know much about @Dynamo (If I am not wrong, he coded the Point system of this forum) but it should be possible to automatize the Holder list using a custom PHP announce/page that reads record from a very basic database table.
