No, no... I've got a much better example (which is actually integrated into Basecamp) - Campfire.
I'm no *real* PHP scripter, so I wouldn't no which way was up, but I know that there are many people who can. And really, I bet there's already a copy of Campfire out there. Does anybody know of one?
I've already integrated PHPFreeChat into aC, and it's quite easy (for me), so imagine how easy it would be for somebody else.
By the way - Campfire rocks out loud. PHPFreeChat is pretty awful and is nowhere near as cool. Somebody should sign up for a free account (www.campfirenow.com) like I have and see what I'm talking about.
I think chatting would be a really cool feature to have as part of activecollab. After a quick Google search, I found Lace (http://socket7.net/lace/). I put a quick demo of this app at my site. I think this could be very useful because it isn't too bloated. It might not take much work to get this into activecollab at all. The only thing might be that there is no database involved, so that might be it's downfall. Maybe not though...
Here's my quick install: http://thinksimpleware.com/lace/
Lace is known to produce serious performance issues in some cases. Add that too activeCollab performance issues and you'll see why integration of two tools at this point is not possible.
ilija, you seem to know about the program: what are the cases, where performances issues arise..... ?? simply too much people ? if so, how many are still ok ?
Lace is AJAX, if I recall correctly... AJAX can really slow down a web browser under any type of use, but especially heavy use. It'd be much better to inetgrate something simple and more static, like refreshing an iFrame (page within a page) or so on... It's quite easy to do this kind of thing. (or so I think)
BTW.. I'm learning PHP now so maybe I can contribute. No promises though! ;)
