How you go about making use of PHP 5 is up to each project. PHP 5.2 in particular adds the ability for PHP apps to give meaningful upload progress meters, for instance. That could be useful for adding attachments to messages. So there are front-end improvements that could be made, independent of the other developer benefits that PHP 5 offers.
That's actually a pretty good idea, I had a look at the code the other day and a progress meter wouldn't be so bad. Would you have a link I could follow?
A little Googling turned up this: http://www.dinke.net/blog/2006/11/04/php-52-upload-progress-meter/en/
Looks like it does require APC and JSON, so it probably can't be a feature that has to work for the system to function, but it is still a very nice add-on for users who have APC enabled. (And if you're running a dedicated box, then you really should have APC on it.)
