CVS via ftp

[David Rasmussen]

Having a local cvs repository at my own machine is all well and good for 
many purposes. But sometimes, I want to be able to check out stuff from 
my repository when I am not at home and my computer is not turned on.

I have a lot of space at an external web hosting facility. The only way 
I can access it is via ftp.

So I am thinking: Is there a way to make cvs place the repository at 
this remote machine using ftp transfers? Does other versioning systems 
such as subversion offer this functionality?

If not, am I right in saying that it wouldn't be very hard to implement 
this? After all, instead of the files having names such as 
/whatever/CVS/some_module/foobar.c (or whatever), it would now be 
ftp://somewhere.com/whatever/CVS/some_module/foobar.c (or something like 
that). The functionality of CVS is the same, it is just the actual file 
handling that is different.

Maybe it can be done invisibly if some sort of "map/mount ftp as 
drive/directory" tool existed.
