Adding Sourcegear Vault support

Question

Simple. I use Vault to manage my personal source files. But I don't like to check in/out outside the Delphi IDE.
Delphi XE supports Subversion so I wondered... Could I also get Vault to work with this? If not, are there alternative add-ins for Delphi for free available?

At work, I use a commercial product as Vault add-in. This is not an option for my work at home, which are just hobby-projects... Vault is also supported by Visual Studio so with Prism, it works. But the Delphi IDE doesn't.
Btw, Sourcegear Vault is free for single-user environments. To quote:

Somebody said that Vault is FREE for a single user. Is this true?
Yes. Vault is free for use by a single user. Simply install the product and do not enter any serial numbers at all. When no serial numbers are present, Vault behaves as if there is exactly one user license. Note that this free license does not apply when the product is used by more than one person. If you have two people who need to use Vault, you will need to purchase two initial licenses. If you enter a serial number containing only one license, then the product will still have exactly one license present. And to be honest, it works very fine in my own single-user environment. :-)

Available options:

1. You use and modify the SVN integration code you can find on SourceForge (although IMHO it's not a good implementation, especially the menu layout).
2. You write a whole integration on your own using the OpenTool API (it could be a bit complex if you never worked with it)
3. If Vault supports the MS SCC interface (it should, if it works in VS), you can buy a plug in like SourceConnexion that adds SCC support to Delphi. Don't know if there is a version for XE already
