I don't know from my own experience, but I do recall that initial
versions of Tribal Trouble [1] did this to manage their updates.

I just downloaded the current version, and have found that they
apparently still use this method, at least on the Mac. (Mac OS X
includes a Subversion client.) I assume it must be working for them.
One technical aspect that worries me with this solution is the
relative fragility of an Subversion working copy. What state will the
working copy be left it if, for example, the network connection drops
during an update? Will your software be smart enough to svn clean? If
that doesn't work, will it punt to the user (bad usability), or do a
fresh check out? These issues are not insoluble, but will need some
thought.
