Does Trillian have any plans to make their own network?

Not that I know of.

Odigo did that (or tried to). They basically did the same thing as Trillian, make a client that talks on multiple networks, but in their case they also had their own Odigo network.

I eventually switched from Odigo to Trillian because the Trillian software is better and they are quicker about responding to AOL's ECMs. Haven't looked back, I wonder how the Odigo people are doing these days?

Still using the Odigo3 skin on my Trillian client, though.
