I intend to add a mechanism to a site which allows registered members to live-chat with one another, IRC-style. I've already loaded Mibbit IRC chat but it's not the right solution for this environment:
A single domain has multiple sub-domains. Each subdomain runs a unique instance of the SMF forum, and thus has unique membership. Some individuals from one group might be in another but they could have a different profile in each group. So for purposes here there's no cross-over. (Yes, I'm looking at multi-site options. There are pros and cons with both single-instance/multi-site and multi-instance topologies.)
So each subdomain needs its own isolated chat area. Member "John" in one group can be different from "John" in another. Again, no cross-over.
IRC doesn't work because on a single server each user has a unique nick, and I don't want channels where everyone is identified as "name_group".
I'm considering BlaB! from http://hot-things.net/. Any comments?
Does DH have restrictions or concerns here? Do I need to discuss this with DH before implementation? I can provide links to DH personnel off-list for the site, forum, etc so DH can see what we're planning.
I have no idea how much this is going to scale. I don't expect this to be a primary use of the site. This is just one feature of many communications options. I've started development on a shared host and will test with a couple groups just to get established. If we need to scale we'll go with one or more VPS's.
