In particular, Perforce has a very nice lightweight branching model so it
is easy to give someone a Perforce account and a private branch they are
allowed to commit to. That's a nice feature for an open source project.

You do have to be a committer to do this.

For people with less than stellar net connectivity, cvsup and a local CVS
repo are much easier to work with. Perforce was built with a LAN in mind
and scales reasonably well to the Internet, but can be painful unless you
have relatively low latency and relatively high bandwidth to the server.
cvsup updates much faster on slow links, too.
A few years ago Perforce was working on a write-through cache so you could
have a local duplicate of the server environment, but I haven't seen that
work come out of the company. That would've rocked for our development
model.
