Why are you so allergic to temporary files?  In most cases they won't be 
significantly slower, as the bulk of the time is for Python to format 
the data as ASCII data, which has to be done anyway.

Write yourself a little helper function like utils.write_array() but 
which is smart about date-formatted data.  File PlotItems can take 
arbitrary strings as their "using" argument.  What else do you need?
