I'm still somewhat against autoupdate.

Think about it ... say for a 1kB feed autoupdate every
10 mins, and for the sake of the argument the computer
is on 8hrs a day for 20days a month (very, very modest
assumption), that's 

  0.001 x 6 x 8 x 20 = 0.96MB ~ 1MB per month/user

Now say there are 10,000 of these modest user all
around the world, then that becomes a 10GB per month
load on the rss feed server.

And that's only the cost for ONE feed.

If autoupdate must be included, I suggest that Sage
must support TTL in full. Otherwise RSS would
eventually be costing too much for providers and would
no longer be available for free, and as someone who
rely on rss heavily, I really don't want to see that happen.
