Much of Xiki has recently been extracted out into the 'xiki' shell command though. So when the vim Xiki client works, a lot of stuff will work (most of the menus). It just needs to grab the path based on where the cursor is, pass it to the 'xiki' shell command, and insert the results into the vim window (indented 2 spaces lower).
If any vim user in the bay area are interested in getting together and pair programming on knocking this out, ping me on twitter! The current vim xiki proof of concept uses the vim ruby api, which is actually pretty decent.
If you're on a Mac, you install AquaMacs which is very mac-like (shift-arrow-key to select, type to replace, etc.) and doesn't require emacs skills.
Another option is for vim people is Viper mode, which emulates vim from inside emacs (a lot of people like it apparently).
Related note, I was pairing with someone on Monday at Proto Night (protonight.com) and we got a very simple TextMate xiki client mostly working.
