is a wiki engine based on a cvs/svn a good idea?

[piotr maliński]

I'm planning to wite a fully featured wiki in Python in one of
frameworks. I've seen some notes about wiki/documentation management
scripts that use SVN as a data storage/versioning.
I've been using SVN a bit but I don't know if it's a good idea to use
it in a wiki engine. Pro: versioning / diffs, Cons: you need your own
svn/cvs repository, can pyLucene or Xapwrap index this?
