http://social.biowar...5/index/2379647Made a topic about this a while ago, also came to the conclusion that the Shadow Broker is a drell. Thane would make no sense, considering the fact that he can die. It would be a brilliant move by BioWare to put someone like the Shadow Broker on your team like that, but they'd have no way of keeping up with the amount of things that could happen to him. He could die on the suicide mission, he might be loyal, he might see his son become just like him, he might never be recruited at all... and that's without even considering his status as possible love interest for FemShep.
Allow me to quote myself:

"Oh look, it's this topic again."
Yeah, it sure is. I though it might be relevant enough to dedicate an entire thread to it considering the fact that he makes an appearance in the Redemption comic, albeit in holographic form:

Even though it might just be some kind of avatar instead of actually being the Shadow Broker's silhouette, the shape of his head suggests that he is a drell, without a doubt the rarest species in the Mass Effect series so far. So rare, in fact, that we have only seen three so far. The first two are obvious: assassin Thane Krios and his son, Kolyat. The third, however, is exclusive the Mass Effect: Redemption comic: Feron, an agent of the Shadow Broker who joins Liara on her quest to save Shepard's body from none other than the Shadow Broker himself. In the end he ends up getting captured by the Broker's enforcer, Tazzik... or did he?
I find it to be highly unlikely that the Shadow Broker turns out to be someone, or something, we never knew. Revealing the identity of an entity this mysterious and intriguing will no doubt be one of the memorable moments of the series, and thus it will probably be a shocking revelation to say the least. A random volus or asari would not have the same impact as someone you may know and possibly care about.
Wouldn't having Liara's new friend turning out to be the Shadow Broker be a great twist? I can definitely see BioWare pulling a Keyser Söze like that, which would also change how one would look at the comic: the legendary Shadow Broker turning out to have been playing with Liara, Cerberus and the Collectors/Harbinger all along, never intending to sell the hero of the Battle of the Citadel to the Collector, but furthering his own goals all along...
In any case, whoever - or whatever - the Shadow Broker may actually be, tell me and the rest of the community about who you think he - or she, or it, or they - is.

Personally, I think the Shadow Broker is an extension of the League of One. If you remember, there is the possibility of a 13th member of the League, who eluded the salarian military. That one salarian could have created a network that grew to what we know of today.
I'm fully aware that this is just a guess, but I think it's a good one, considering the salarian penchant for information warfare (espianoge, etc.).
Also considered that, which would be in line with Kirrahe's speech, the part about the STG's heroes: "...or the Ever Alert, who kept armies at bay with hidden facts." We do not know when this "Ever Alert" existed, so he might not be the current Shadow Broker, but he could be the one that started it.
