Right now VaultPress is for standalone instances of WordPress only, but the question on everyone’s mind seems to be: what about MU + MS? With the merge of MU and WordPress into MS (multi-site) with 3.0 I’m not surprised it’s a hot topic.
For WordPress MS users, we just need to figure a few things out first, namely billing and enumerating your blogs. On the tech side, hooking into MS is not going to be hard since it’s basically just a bunch of WordPresses. VaultPress support is great, if say, your server goes away and takes 73,000 blogs with it.
(As an aside, we’ve just started sending out invites to allow existing customers to purchase coverage for a second blog.)
BuddyPress, bbPress… that’s another blog post.
