Thanks for the feedback. It's difficult to know what to put on the main 
page and what to leave out.

Every program you've run at least once is on your system, unless you 
explicitly removed it. To see the list, do:

$ 0launch --gui

Then click on 'Show Cache'.

There is one subdirectory in your cache for each version of each package. 
All of a package's files are contained inside its directory. If you want 
to remove a package, deleting its directory is sufficient.

It would be a poor system indeed that didn't support that ;-) I run most 
of my desktop using Zero Install, and I'd be pretty annoyed if it stopped 
working every time I went on a plane!

What kind of control are you looking for? A directory is added for each 
new version of every program you add. Directories are removed when you 
delete them.

As in the URL-based scheme you that proposed at the start of this thread, 
this isn't the case. If you have access to the software from some other 
source (e.g. a CD) then you can use that instead.

You could always delete them. Personally, I find hard-disk space is 
growing faster than the amount of software I use and hasn't been a 
limiting factor for some time ;-) We might be smarter about this in the 
future (e.g. something like "deborphan").

You could even delete the entire cache (~/.cache/0install.net normally, 
or /var/cache/0install.net if you enabled sharing between users).
