Yep, I also faced the same problem; especially when hacking on a script locally and forget the changed file to upload. This one always lets me shout and curse ;-)

I've taught myself to use CVS for almost everything. How many times this has saved my butt I can't tell you, but it's been a lot! Unfortunately, this does not help you with the problem I sketched above.
To address this, I wrote a simple bash which takes the name of the file I'm editting. It sleeps normally for 15 seconds, peeks wheter the file has been modified, and if so, uploads it to its remote place. It saves me a lot of time, that I can assure you... (it is also never been so quite in my home :-)
