One very random idea for this kind of thing would be to use the
software behind the IRI Data Library:

http://iridl.ldeo.columbia.edu/index.html

It has a built in processing language ('ingrid') for manipulating data
on the server before returning it to the client, supports multiple
output map formats, data selection, non-spatial data, high-dimensional
data etc etc. You can map stuff and download it:

http://iridl.ldeo.columbia.edu/SOURCES/.NASA/.GPCP/.V2p1/.AGPI/figviewer.html?plottype=colors

and it's apparently easy to write server-side processing modules to
provide add-on functionality by writing new ingrid functions.

The only problem is that the code behind it doesn't seem to be
available, which is a real shame...
