As i understand we shouldn’‘t talk here about how useful it is (and it does), but about traffic and security issues. Well i’'m not a specialist about network/traffic, but we werent even concerning about that setting up internal IM server for a ~70 (now ~100) users. Of course, only messaging, no file transfers. How much can it take? And waht about AIM/etc.? They are not messaging by air too Anyway, we arent having any troubles with our network after setting up Wildfire/Exodus.
Security question was already discussed and i agree. It’‘s local, it’'s closed, or you can let it connect to other servers. But it can be monitored. If commmunity needs to im about some work stuff i think it SHOULD be some internal service and not AIM/MSN/etc based.
And other reasons for internal IM network. You dont suffer because of AIM/MSN or you ISP breakdowns. Everyone in your community can talk to other, unlike the case the one like AIM and other prefers MSN. Of course you can use Miranda, Trillian, Gaim to support every network.
You dont have to teach or register by yourself every user with particular networks. MSN registration is really complicated, even for me, an IT guy. So with one IM network you dont have to keep in mind every registration step, no confirmation emails, dont have to remember every user’'s passwords
Flexibility. Everything you can control. You can enable registration by users. You can regiter them by yourself. You can create and share groups. You dont have to create groups for every user individually.
New ways of interactions. At our company IM client is installed for every user. So, even those who never before knew about IM are using it constantly. It’'s more convinient and faster than email and cheaper than phone calling. And you can talk with a few people at once (not necessary in conference mode).
This is fun Well. Of course IM is always some kind of distraction. But i think this is also some kind of terapy. While you’‘re working hard all the day it’‘s good to have few minutes to chat with co-workers, not holding the phone line. Especially if the one you’'re talking to is on the other side of building
