background task to wget Fedora 18

[Robert Moskowitz]

Well the new release is out, and I am away at IEEE 802 wireless meeting 
across the continent from my server.

Normally when I am fetching a new distro, I am local and VNC into my 
server (over SSH), open a terminal window and start the wget.  At any 
time I can reopen a VNC connection and see how the download(s) is 
doing.  But from here it is a number of island hops to get to that 
server, and does not always work.  I CAN do only moderately painful via 
a number off SSH hops.  So other than adding the wget(s) to crontab (I 
will do that anyway for the updates tree), or ending the wget command 
with '&' (and then not really knowing when it completes), how might I 
best remotely trigger these downloads so when I get home friday, they 
are there for me to work on?
