Here is a link to a blog that goes into great detail on how to fab your own sram module for the Mega.

This guy talks about doing compression on a microcontroller... with enough memory, perhaps it's possible to generate deltas from the high datarate stream, and then compress the end result to give us the most bang for our iridium-lined buck.

NEED MOAR RAM!

awesome idea!

And I'm no programmer, but would using STL help with the storage and handling of the data in the Arduino? It seems like it would make certain functions easier to write.

Looks like STL was ported early this year, and the SRAM stuff was talked about in August. Would have been handy to had this stuff a year ago :)

STL objects have a pretty huge RAM + Processor overhead, probably not tenable.

wow and they even tossed in a very nice hardware serial stream: This allows you to drop the clunky println() calls and use the more elegant streams

You might want to follow the early links in this discussion Brad.  Tim is laying out a Comm Controller PCB Arduino Mega with 512 kilobytes of RAM onboard!

I am following the links.  Andy Brown has done a very good job at finding and customizing a tiny STL, but you're still going to get a lot of RAM and CPU thrashing with excessive string manipulation.  512k is enough that this *probably* won't be an issue (except maybe the CPU thrashing), but I was unaware the such a controller was in the works.  With a stock 2560, you'd be hurting.
