And what if I as a user switch on this feature, having been advised by
the manuals ("switch this feature on if your server is on the LAN")
having totally forgotten that lurking around on my harddrive are working
copies of open-source projects (including TSVN) that I checked out long
ago. What if thousands of other people make that same mistake? we all
unwittingly are bombarding the servers with svn status requests.

Now supposing you ran the status cache in shell mode instead of default
mode, it would presumably have to do (remote) status request every time
you opened a directory in explorer - I reckon explorer would become
unusable and the good people who develop TSVN would be bombarded with
complaints...

You could deliberatly poll a server every two seconds, but with this
feature you could accidentally poll several servers you didn't know about.

I reckon that if you rely on overlays to show remote status it leads to
a false sense of security. How can you be sure its absolutely up to
date, you can't even be that sure with the local status (although it's
pretty quick on a good PC). If you really want to now "right now" that
a file is remotely unchanged to you need to perform the check "right
now" and that's what the check for modifications dialog does.

I've been using TSVN for 3 years and I always find that this issue
confuses new people for about the first day then they get used to it
(then they get to like it? I don't know but I certainly like the SVN
philosophy that you only get bothered by remote status when you go
looking for it...)
