New Blog Templates- does it work cross networks?

If you have 2 or more networks set up, can this be used between network sites, or just on one network?

So, if you have a classified site all set up, that you want to use as default for other classified sites, would you need to set this up on each multisite network, or can you use it also on the other multisite networks?

If you can't use cross networks, can you suggest it as feature to add to it?

Also, if you can't, is there a way to clone it from one network to another?

Thanks,
Tom
