Thank you for the kind words!  What grid are you using for your  
backups -- the allmydata.com prouction grid?

Great!  We could use yet another picky, demanding user to identify  
exactly what parts of the documentation need improving.  ;-)

This is ticket #578.  If I recall correctly it is actually just a  
shallow user interface issue -- the underlying machinery will work if  
you pass it a verify cap but the UI frontends incorrectly require a  
readcap.  If that recollection of mine is true then we should add the  
tag "easy" to that ticket.

Hm, that server is down at the moment.  We at allmydata.com had a  
clever idea to make our servers boot from USB flash drives so that we  
could use the entirety of each hard drive for storage instead of for  
the boot and root files.  Unfortunately USB flash drives turn out to  
be extremely short-lived in our experience.  We've probably burned  
through two dozen of them and we need to replace four more now to  
bring up four of our servers.  One of those servers that is currently  
down is helper.allmydata.com.

Now we could set up another server to act as a helper and give you  
the furl to it and you could use that.  I'll get back to you.
