OK. So if we did cache svn checkouts, that would help in that you wouldn't have to spend a lot of time downloading, but you would still have unnecessary files on disk.

Recent versions of svn include pretty good support for sparse checkouts, but MacPorts doesn't have any support for that, so if you wanted to make use of that you'd have to write custom fetch code again. :/

In this case I'd probably set svn.url to the "main" URL, i.e. whichever URL will provide the largest amount of data, and then use a post-fetch block to get the rest of them. This way if we do eventually cache the checkout from the svn.url, you'll get the biggest benefit.
