I got some really difficult interrupt driven state machine style image compression code I created to succeed at my work yesterday. I am going to continue to put my nose to the grindstone on some other difficult coding tasks in the coming weeks as the opportunities for what I am creating are huge.
Sounds like you're trying to do multiple images or video streams at once perhaps? I hear the state machine stuff, writing something to emulate threads when you have no threads and it has to fit in a few k of rom is a b*tch.
Now, try doing something similar in a web server that has no state. You have a whole new can of worms.
